SAMARITANS OR SAMARIANS?
As mentioned earlier, the traditional view of the origins of Samaritans is based on II Kings 17. The verse in question is II Kings 17:29 where the Hebrew word shomronim or shomeronim
appears and is usually translated into English as "Samaritans" (underlined in the Hebrew text below).

But every nation still made gods of its own, and put them in the shrines of the high places which the Samaritans had made, every nation in the cities which they dwelt... (RSV)
The name shomronim that appears in II Kings 17:29 is associated with the worship of idols. However, the Samaritans do not address themselves by this name at all. They call themselves shamerin 
, that is "keepers" or "observers" of the Torah.[13] The Samaritans themselves make a clear distinction between their own ancestors and the inhabitants of Samaria. For example, in the part of the Samaritan Chronicle II which corresponds to I Kings 16 of the Hebrew Bible, the biblical account of the founding of Samaria by Omri is followed by a note which explains that the inhabitants of Samaria and its nearby cities were called "Shomronim after the name Shomron".[14] Thus the distinction between the people of Samaria and the Samaritans is clearly maintained in the Samaritan Chronicle II. Put simply, shomronim means the "inhabitants of Samaria" and it has nothing to do with shamerin, "keepers" or "observers" of the Torah, which the Samaritans use for themselves. In fact, a long line of Samaritan scholarship has already pointed out this fact, which, unfortunately, is ignored by the missionaries at their own peril. For example, about 100 years ago James Montgomery pointed out that the Samaritans:
.... call themselves by the ancient geographical apellative, Samerim, which they interpret however as meaning "the Observers", i.e., of the Law.[15]
Similarly, The Interpreter's Dictionary Of The Bible confirms that:
.. the Samaritans prefer to style themselves 'Shamerim'
i.e., "the observant" - rather than 'Shomeronim'
i.e., "the inhabitants of Samaria."[16]
The Encyclopaedia Judaica under the entry "Samaritans" says:
Little guidance is obtained from the name of the Samaritans. The Bible uses the name Shomronim once, in II Kings 17:29, but this probably means Samarians rather than Samaritans. The Samaritans themselves do not use the name at all; they have long called themselves Shamerin; i.e., "keepers" or "observers" of the truth = al ha-amet, both the short and long forms being in constant use in their chronicles. They take the name Shomronim to mean inhabitants of the town of Samaria built by Omri (cf. I Kings 16:24), where the probable origin of the word Shomronim is to be found).[17]
Contrary to the claims of the missionaries, the use of the term shomronim in II Kings 17 tells us nothing about the origins of the Samaritans because this word means "inhabitants of Samaria". Now that the issue of the names that differentiates the Samaritans from the inhabitants of Samaria is dealt with, let us now move to the claim of the missionaries which says that the Samaritans as a distinct people only emerged after the exile of the northern kingdom of Israel and the resettlement of foreigners in the area under king Sargon II after 722 BCE.
II KINGS 17:18-24 - A HISTORICAL NARRATIVE OR A HISTORICAL ABSURDITY?
The narrative in II Kings 17:18-24 relates that the population of Israel in its totality was deported and exchanged to an alien population. However, the archaeological evidence shows that this narrative is incorrect. Estimates of the population in Israel show that in the Middle Bronze Age II [2000 - 1550 BCE] it was approximately 140,000 and in the Iron Age [1200 - 586 BCE],[18] during the period of divided monarchy, the population of northern kingdom of Israel reached nearly 600,000.[19] A survey of Judea, Samaria and the Golan carried out in 1967-1968 suggests a total of 560,000.[20] On the other hand, Roland de Vaux estimated the total population during this time to be around 800,000.[21]
The Assyrian ruler Sargon II was responsible for defeating the northern kingdom of Israel and sending them into exile. An Assyrian inscription from the time of Sargon II records that he deported 27,290 prisoners from Samaria,[22] suggesting a depopulation of the order of nearly 5% of Israel's population.[23] Hence 95% of the population remained. Also it can be claimed that the Assyrian kings in their royal inscriptions tended to exaggerate the number of exiles, as they considered a larger number to show the extent of their power and might.[24] If we accept this, then the total number of people exiled would be further reduced. We are essentially left with most of the population intact. Obviously there is a serious historical problem here with II Kings 17:18-24. Commenting on this historical discrepancy and how it undermines the Bible concerning the claim of the Samaritans' origins, A. D. Crown says:
This is a prima facie evidence that the greatest concentration of people remained in the province until at least sixth century B.C.E. Clearly the story of Samaritan origins in the Bible must be viewed with caution.[25]
A similar observation was made by Coggins about 30 years ago. Using the estimate of Roland de Vaux of 800,000 people in the northern kingdom of Israel and the inscription from the time of Sargon II, he says:
If this is at all accurate it would imply the deportation of between 3 and 4% of the population. Not much stress can be placed on the actual wording of the Assyrian annals, but they would suggest - and the circumstances of a siege would bear out - that the majority of the deportees would have been the inhabitants of Samaria itself, no doubt including many who had gone there as refugees during the siege.[26]
Such discrepancies were also mentioned by Frank Cross[27] and The Interpreter's Dictionary Of The Bible.[28]
Coggins and others have suggested that most of the affected people would have been from the upper class, as they would be readily identifiable as potential leaders of resistance.[29] In place of those exiled, the settlers brought in would not have enjoyed the majority, as the native Israelites continued to enjoy being the overwhelming majority of the population. Clearly, the narrative in II Kings 17:18-24 claiming that the population of Israel in its totality was deported by the Assyrians and exchanged to an alien population is unsupported by the archaeological evidence.
How do the Samaritans portray themselves during the period of Assyrian rule? According to their Chronicles, the righteous remnants who belonged to "the community of the Samaritan Israelites, that is the tribe of Ephraim and the tribe of Manasseh, sons of Joseph, and a few other priests and a small number from the rest of the tribes of Israel" who "did not deviate from the way of the holy law, nor did they worship other gods. They did not behave as the nations did, and did not forsake the chosen place Mount Gerizim Bethel, but they continued to worship the Lord their God...".[30] As Coggins pointed out, even if this idealization is discounted in the Samaritan Chronicles, it is clear that the "religious features of later Samaritanism show no sign of any syncretism brought about by a mixture between native Israelites and those whom the Assyrians brought into the country".[31]
Unlike the claim of the Christian missionaries, there is nothing to suggest in the Samaritan Chronicles that they adopted a syncretism between the religion of the Jews and their own polytheistic background. On the contrary, the Chronicles clearly affirm their monotheism during the Assyrian rule. It must be emphasized that the Samaritans' devotion to the Torah was already recognized from the fact that it alone constituted their canon of Scripture. This is further emphasized by the word shamerin - the keepers of the Torah. This very name implies a group which maintained the traditional ways and was suspicious of change.
AN APPRAISAL OF THE MISSIONARY VIEWS
The Christian missionaries and apologists have had some difficulty in coming to terms with Samaritan scholarship. Although this is partly due to basic errors in comprehension, more seriously, it is primarily due to the fact that contemporary scholarship including the archaeological evidence undermines the veracity of the biblical account. Recognising these basic problems of method, the missionaries have attempted to synthesise their views on the Samaritans into one coherent account; resultantly we are left with nothing more than a mishmash of interpretations with little validity. For instance, consider the Christian missionary Andrew Vargo's "three views " of the Samaritan origins:
The Jewish view. The Samaritans are the descendants of the colonists that King Shalmaneser, of Assyria, brought from Cutha, Babylon, Hamath, and other foreign regions after he conquered Samaria in 722 B.C.. King Shalmaneser then deported the native population according to II Kings 17.
Samaritan view: The Samaritans are remnants of the northern Israelite tribes who were left behind when their brethren were deported by the Assyrians.
Modern Scholars: The Samaritans are descendents of Mesopotamian tribes who were deported by the Assyrians and Babylonians to Samaria.
He claims that "all three explanations of the origins of the Samaritans are correct, at least to some degree". It is hard to see why all the three "explanations" can be true to "some degree" at the same time. Simple logic dictates that if the "Samaritans are remnants of the northern Israelite tribes" then they could not have been simultaneously "the descendants of the colonists" resettled by the Assyrian rulers. Furthermore, Vargo claims on behalf of unnamed and unknown "modern scholars" that the Samaritans are "the descendents of Mesopotamian tribes who were deported by the Assyrians and Babylonians to Samaria". In fact, we have not come across this view at all in modern scholarship on the Samaritans. What we know is that modern Samaritan scholarship has firmly rejected equating shomronim in II Kings 17:29 with Samaritans. Shomronim means the "inhabitants of Samaria" and it has nothing to do with shamerin, "keepers" or "observers" of the Torah, which the Samaritans use for themselves. Moreover, it was seen that there are serious historical problems with II Kings 17:18-24 which severely undermines the biblical account concerning the claims of the Samaritan origins.
To complete the argument what does modern scholarship say about II Kings 17 being the alleged source of the Samaritans' origins? Let us start with A Companion To Samaritan Studies published in 1993. One can consider it as a dictionary 'desk reference' for Samaritan studies. As for II Kings 17 and the origins of the Samaritans, it says:
Older scholarship took 2 Kings 17 as a reliable account of the origins of Samaritanism and in many translations that is the only place where the word Samaritans is found in the Hebrew Bible (e.g. KJV, RSV). The idea that this passage can give us information about the Samaritan origins is now abandoned though it is undeniable that at an early date the text of understood in this sense. Thus Josephus (Ant. 9:291) states that the heterodox community formed after the Assyrian capture of Samaria was the direct forerunner of the Samaritan or Cuthaean community of his day. Egger has shown how many of Josephus' references to the Samaritans cannot properly be understood of the Samaritan religious community. Josephus' work is a clear example of anti-Samaritan polemic at work extrapolating materials from one setting to another as part of his condemnation of the Samaritans.[32]
Similar conclusions were also reached by Lester Grabbe. He says:
The origins of the [Samaritan] community and cult are still uncertain. The origins according to interpretations of 2 Kings 17 (pagan foreigners brought in) and Josephus (dissident Jerusalem priests) are the product of considerable bias and cannot be taken at face value.[33]
Writing in 2002, Anderson and Giles in their book The Keepers: An Introduction To The History And Culture Of The Samaritans say that II Kings 17 cannot be considered an objective account of Samaritan history:
The Cutheans are simply the inhabitants of the north, not the Samaritan sect. Sargon's deportation of the indigenous Israelite population probably affected primarily the aristocracy within the city of Samaria. The people groups brought into the region replacing the deportees remained a minority. The invectives of the 2 Kings account address this select few and not the general population, and certainly not a religious sect [i.e., the Samaritans] that had, according to the bulk of evidence, not yet attained a sense of self-awareness.
...
It is generally recognized that the account in 2 Kings 17 is not objective and unbiased history. The purpose of 2 Kings 17, as well as other passages in the Hebrew Bible (particularly in Chronicles and Ezra), is to highlight the primacy of Jerusalem over any potential rivals.[34]
After examining the evidence, Anderson and Giles conclude that the Samaritans did exist during the time of Assyrian invasion, not as a separate sect but as a part of the northern kingdom of Israel. In other words, Samaritans did not emerge after the exile of the northern kingdom of Israel and the resettlement of the area under king Sargon II after 722 BCE.
After doing a detailed discussion on the alleged presence of the Samaritans in II Kings 17, Coggins concluded that:
The simple truth is, as it is hoped that the first main part of the study has shown, that there is no reference to the Samaritans in the Hebrew Old Testament. Some of the allusions in the work of the Chronicler may point to a situation which would later develop into Judaeo-Samaritan hostility, but that is most that can be said.[35]
The New Bible Dictionary under the entry "Samaritans" says:
... Samaritans are mentioned only in 2 Ki. 17:29, a passage which describes the syncretistic religion of those peoples whom the king of Assyria transported to the N kingdom of Israel to replace the exiled native population after the fall of Samaria (722/721 BC).
Several reasons argue strongly against the identification, favoured by Josephus and many others since, of this group with the Samaritans as they are more widely known from the NT..., some of whose descendents survive to the present day in two small communities at Nablus and Holon: (i) the word used (hamrnîm) seems merely to mean 'inhabitants of (the city or province of) Samaria (mrôn)', and this fits the context of 2 Ki. 17 best; (ii) there is no evidence that the later Samaritans inhabited Samaria. The earliest certain references to them, by contrast, all points clearly to their residence at Shechem..., whilst one of the Josephus' sources refers to them as 'Shechemites'...; (iii) nothing whatever that is known of later Samaritan religion and practice suggests the pagan influence of 2 Ki. 17 or Ezr. 4.[36]
It is worthwhile adding that modern biblical scholarship has recognized that antagonism between the kingdoms of Judah and Israel existed for many centuries which goes back to the period of the united monarchy. The account in II Kings 17 was written from a southern viewpoint and was quick to highlight the primacy of Jerusalem over any potential rivals. Independence from Jerusalem, an identifying characteristic of Samaritanism, draws unqualified criticism in the Hebrew Bible.[37] Modern Samaritan scholarship also realizes that there was no sudden break that separated Jews and Samaritans. Rather, the rift developed over a long period of time with certain events causing more hostility than others.[38] Perhaps it was after John Hyrcanus destroyed the temple on Mount Gerizim in 2nd century BCE, the two communities went separate ways.
To summarize, modern scholarship conclusively refutes the claim of Samaritan origins based on II Kings 17. The Christian missionary and apologist views, including Vargo's "Jewish view" and the views of his unknown and unnamed "modern scholars", can now be safely discarded.
