2 Kings 23:29

The king, &c. — The king of Babylon, who having formerly rebelled against the Assyrian had now conquered him; as appears by the course of the sacred, and the concurrence of the prophane history; and therefore is here and elsewhere called the Assyrian, and the king of Assyria, because now he was the head of that empire. Euphrates — Against Carchemish by Euphrates, as it is expressed, 2 Chronicles 35:20, which the Assyrian had taken from Pharaoh's confederates, who therefore sends forces against the Assyrian, that he might both help them, and secure himself. Josiah went — Either to defend his own country from Pharaoh's incursions; or to assist the king of Babylon, with whom he seems to have been in league. Slew — Gave him his death wound there; though he died not 'till he came to Jerusalem. Seen him — When he fought with him, or in the first onset. It does not appear, that Josiah had any clear call to engage in this war; possibly he received his death wound, as a punishment of his rashness.
