Albert Barnes Commentary Jeremiah 44:8

"in that ye provoke me unto anger with the works of your hands, burning incense unto other gods in the land of Egypt, whither ye are gone to sojourn; that ye may be cut off, and that ye may be a curse and a reproach among all the nations of the earth?" — Jeremiah 44:8 (ASV)

Cut yourselves off - Rather, cut (them, Jeremiah 44:7) off from you.
