John Gill

And they shall fight against thee,.... The Targum adds, "that they may hide the words of thy prophecy;'' hinder him from prophesying, stop his mouth, and even take away his life: but they shall not prevail against thee; as to do either: for I am with thee, saith the Lord, to deliver thee; as he did; he hid him when they sought for him, and delivered him out of the dungeon and bonds into which he was cast by them; See Gill on Jer 1:8.
