After a decisive battle between Egypt and Babylon, the power of Egypt was gone. As if the writer wants to say: It is logical that Jehoiakim did not receive any more help from Egypt, isn’t it?!
The prophet Jeremiah has said more than once that the Lord will punish Judah and that he will use Babylon to do so. Thus, seeking help from Egypt is both going against the will and judgment of the Lord and also denying the political-military reality that means Egypt has been dethroned as a world power by Babylon.
7 Le roi d'Egypte ne sortit plus de son pays, car le roi de Babylone avait pris tout ce qui était au roi d'Egypte depuis le torrent d'Egypte jusqu'au fleuve de l'Euphrate.
