Charles Ellicott Commentary 2 Kings 24:7

"And the king of Egypt came not again any more out of his land; for the king of Babylon had taken, from the brook of Egypt unto the river Euphrates, all that pertained to the king of Egypt." — 2 Kings 24:7 (ASV)

And the king of Egypt came not again any more ... —The verse indicates the state of political affairs at the time when Jehoiachin succeeded his father. Necho had been deprived by Nebuchadnezzar of all his conquests and so crippled that he dared not venture again beyond his own borders. Thus Judah was left, stripped of all external help, to face the consequences of its revolt from Babylon, which speedily overtook it (2 Kings 24:10).

From the river (torrent) of Egypt — that is, the Wady-el-Arish. The details of this campaign of Nebuchadnezzar are not recorded. It is clear, from the statement before us, that before the battle of Carchemish Necho had gained control of the whole of Syria and the country east of the Jordan.
