Jeremiah 46:2 - Joseph Benson’s Commentary on the Old and New Testaments

Against Egypt, against the army of Pharaoh-necho Pharaoh- necho was king of Egypt in Josiah's time, and it was by his army that Josiah was killed at Megiddo, as is related 2 Kings 23:29, where see the note. That army was then marching under the conduct of Necho against the Medes and Babylonians, who, having by the capture of Nineveh destroyed the Assyrian empire, had become formidable to the neighbouring states. Josiah opposed it in its march through the country, but was defeated, and received a wound in the battle which proved mortal. Necho continued his march after this victory, defeated the Babylonians, took Carchemish, and securing it with a strong garrison, returned into his own country. Nabopolassar, the king of Babylon, observing that all Syria and Palestine had revolted on account of the reduction of Carchemish by the Egyptians, sent his son Nebuchadnezzar with an army to retake that city, and recover the revolted provinces. Necho marched with a powerful army to oppose him; and it appears it was at the time when the Egyptian army lay along the banks of the Euphrates, waiting to oppose the entrance of Nebuchadnezzar into Syria, that this prophecy was delivered, namely, as is here said, in the fourth year of Jehoiakim. The two armies came to an engagement near the city of Carchemish, and the event of the battle proved very disastrous to the Egyptians, who were routed with prodigious slaughter, as is here foretold by the prophet in a very animated style, and with great poetic energy and liveliness of colouring.
