Idumea, Palestine, Phoenicia, and Syria submitted to him, and for three years he remained in undisturbed possession of his conquest.

Then, however, the Babylonians, who had received these provinces at the division of the Assyrian Empire, began to bestir themselves.

Nebuchadnezzar marched to Carchemish, defeated the army of Neco, recovered all the territory to the border of Egypt, and even ravaged a portion of that country.

It is probable that in this expedition he was assisted by the Medes.

At any rate, seven or eight years afterwards, when the intrigues of Egypt had again created disturbances in this quarter, and Jehoiakim, the Jewish king, broke into open insurrection, the Median monarch sent a contingent, which accompanied Nebuchadnezzar into Judaea, and assisted him to establish his power firmly in South-Western Asia.
This is the last act that we can ascribe to the great Median king.
