Albert Barnes Commentary Jeremiah 30:14

"All thy lovers have forgotten thee; they seek thee not: for I have wounded thee with the wound of an enemy, with the chastisement of a cruel one, for the greatness of thine iniquity, because thy sins were increased." — Jeremiah 30:14 (ASV)

For the multitude ... - Or,

Because of the multitude of thine iniquity,

Because thy sins are strong.

Judah’s lovers are the nations which once sought her alliance (Jeremiah 27:3).
