That having heard, on the return of the embassy (Elasah and Gemariah, whom Zedekiah had sent to Babylon, and to whom the prophet entrusted the above letter, Jeremiah 29:3;), that the captives had not received his advises favourably, because they were deceived by false prophets among them, who promised them a speedier deliverance, he therefore wrote a second letter, beginning with the fifteenth verse, and going on with the twenty-first, etc., in which he denounces God's judgments on three of the chief of those, Ahab, Zedekiah, and Shemaiah.

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 27:3.
Jeremiah 29:17
Vile - The word does not occur elsewhere, but comes from a root signifying to shudder, and thus has an intense meaning.
