Jeremiah 46:10 - Ellicott's Commentary On The Whole Bible

This is the day of the Lord God of hosts. — The prophet contemplates the issue of all these great preparations, and sees that they will end in a disastrous overthrow, the righteous retribution for long years of cruelty and outrage. In doing so he falls back upon the language of earlier prophets (Isaiah 34:8; Zephaniah 1:7), in part also upon that of Deuteronomy 32:42. There is to be a “great sacrifice,” and the army of Egypt is the destined victim; and the banks of the Euphrates (i.e., Carchemish) are to be as the altar.
