2 Kings 17:4 - Albert Barnes' Notes on the Bible

So, king of Egypt, is generally identified with Shebek (730 B.C.), the Sabaco of Herodotus. Hoshea’s application to him was a return to a policy which had been successful in the reign of Jeroboam I (1 Kings 12:20 note), but had not been resorted to by any other Israelite monarch. Egypt had for many years been weak, but Sabaco was a conqueror, who at the head of the swarthy hordes of Ethiopia had invaded Egypt and made himself master of the country. In the inscriptions of Shebek he boasts to have received tribute from “the king of Shara” (Syria), which is probably his mode of noticing Hoshea’s application. References to the Egyptian proclivities of Hoshea are frequent in the prophet Hosea Hosea 7:11; Hosea 11:1, Hosea 11:5; Hosea 12:4. King Hoshea, simultaneously with his reception as a vassal by Sabaco, ceased to pay tribute to Shalmaneser, thus openly rebelling, and provoking the chastisement which followed.
