Egypt reckoned Sethon the last King of Egypt, who Reigned before the division of Egypt into twelve contemporary Kingdoms, and by consequence before the invasion of Egypt by the Assyrians.
For Asserhadon King of Assyria, in the 68th year of Nabonassar, after he had Reigned about thirty years over Assyria, invaded the Kingdom of Babylon, and then carried into captivity many people from Babylon, and Cuthah, and Ava, and Hamath, and Sepharvaim, placing them in the Regions of Samaria and Damascus: and from thence they carried into Babylonia and Assyria the remainder of the people of Israel and Syria, which had been left there by Tiglath-pileser. This captivity was 65 years after the first year of Ahaz, Isa. vii. 1, 8. & 2. King. xv. 37. & xvi. 5. and by consequence in the twentieth year of Manasseh, Anno Nabonass.* 69. and then Tartan was sent by *Asserhadon with an army against Ashdod or Azoth, a town at that time subject to Judæa, 2 Chron. xxvi. 6. and took it, Isa. xx. 1: and this post being secured, the Assyrians beat the Jews, and captivated Manasseh, and subdued Judæa: and in these wars, Isaiah was saw'd asunder by the command of Manasseh, for prophesying against him. Then the Assyrians invaded and subdued Egypt and Ethiopia, and carried the Egyptians and Ethiopians into captivity, and thereby put an end to the Reign of the Ethiopians over Egypt, Isa. vii. 18. & viii. 7. & x. 11, 12, & xix. 23. & xx. 4. In this war the city No-Ammon or Thebes, which had hitherto continued in a flourishing condition, was miserably wasted and led into captivity, as is described by Nahum, chap. iii. ver. 8, 9, 10; for Nahum wrote after the last invasion of Judæa by the Assyrians, chap. i. ver. 15; and therefore describes this captivity as fresh in memory: and this and other following invasions of Egypt under Nebuchadnezzar and Cambyses, put an end to the glory of that city. Asserhadon Reigned over the Egyptians and Ethiopians three years, Isa. xx. 3, 4. that is until his death, which was in the year of Nabonassar 81, and therefore invaded Egypt, and put an end to the Reign of the Ethiopians over the Egyptians, in the year of Nabonassar 78; so that the Ethiopians under Sabacon, and his successors Sethon and Tirhakah, Reigned over Egypt about 80 years: Herodotus allots 50 years to Sabacon, and Africanus fourteen years to Sethon, and eighteen to Tirhakah.
The division of Egypt into more Kingdoms than one, both before and after the Reign of the Ethiopians, and the conquest of the Egyptians by Asserhadon, the prophet Isaiah [340] seems allude unto in these words: I will set, saith he, *the Egyptians against the *Egyptians_, and they shall fight every one against his brother, and every one against his neighbour, city against city, and Kingdom against Kingdom, and the Spirit of Egypt shall fail.--And the Egyptians will I give over into the hand of a cruel Lord [viz. Asserhadon] and a fierce King shall Reign over them.--Surely the Princes of Zoan [Tanis] are fools, the counsel of the wise Councellors of Pharaoh is become brutish: how long say ye unto Pharaoh, I am the son of the ancient Kings.--The Princes of Zoan are be come fools: the Princes of Noph [Memphis] are deceived,--even they that were the stay of the tribes thereof.--In that day there shall be a high-way out of Egypt into Assyria, and the Egyptians shall serve the Assyrians_.
