These verses are not in the Septuagint. But the text of the Septuagint is here throughout so brief and confused as to be explicable only on the supposition, that it represents what was left behind in Egypt when Jeremiah died, copied probably with extreme haste, and with no opportunity of careful collation afterward. On the other hand the Hebrew text represents no hurried transcript, but the original manuscript, and is especially trustworthy in the case of these letters sent to Babylon (see also Jeremiah 51), because the originals of them would be available for collation with the text preserved by Jeremiah himself. The verses were probably intended to allay excitement in Babylon consequent upon the knowledge that the representatives of various kings were assembled at that very time at Jerusalem to form a coalition against Babylon Jeremiah 27:3.
Vile - The word does not occur elsewhere, but comes from a root signifying to shudder, and thus has an intense meaning.
