2Kgs 17:3

“At this point it is also appropriate to tell where the Samaritans originated. I say this because the entire region is called Samaria. From what source, then, did they derive this name? The mountain is called Semer from the man who had taken possession of it, as Isaiah also said: "And the head of Samaria, Ephraim." The inhabitants, however, were called not Samaritans but Israelites. But as time went on, they transgressed against God, and during the reign of Pekah, Tiglath-pileser went up and seized many cities. After attacking and killing Elah, he gave the kingdom over to Hoshea. Later, Shalmaneser came and captured other cities and made them subject and tributary. However, though Hoshea at first yielded, he revolted afterwards from subjection and took refuge in the aid of the Ethiopians. The Assyrian learned this and, having made an expedition and taken them captive, forbade the nation to remain there any longer, because he suspected the possibility of another such revolt.”
