Matthew Poole and continuators on Jeremiah 46:2

2 Against Egypt, against the army of Pharaoh Necho king of Egypt, which was by the river Euphrates in Carchemish, which Nebuchadrezzar king of Babylon smote in the fourth year of Jehojakim the son of Josiah king of Judah .

Pharaoh Necho was King of Egypt in Iosiahs time, it was by his Army that Iosiah was killed at Megiddo, 2 Kings 23.29. it was he that made Iehojakim King of Iudah taking away I[illegible: 1 letter]hoahaz, ver. 34. but though he prevailed at that time, and that was one time when he came out against Carchemish, 2 Chron. 35.20. yet he was overthrown by N[illegible: 1 letter]buchadnezzar in a Battel with him afterwards as appears from 2 Kings 24.7. and Iehojakim was made Tributary to Nebuchadnezzar as we read 2 Kings 24.1. and the King of Egypt, was brought so low by that victory that he stirred no more out of Egypt for the King of Babylon had taken from him all from Nilus, the great River of Egypt to Euphrates, and this saith this verse was in the 4th. year of Iehojakim. This prophesie must be before that time. Carchemish appeareth from Isa. 10.9. to have been a place in Syria where the Egyptian Army had been in Iosiahs time and then went away conquerers as appears from 2 Chron. 35.20, &c.
