Matthew Poole and continuators on Jeremiah 20:3

3 And it came to pass on the morrow, that Pashur brought forth Jeremiah out of the stocks . Then said Jeremiah unto him, The LORD hath not called thy name Pashur, but Magor-missabib .

Possibly by this time the mad-brain'd Priest, thought he had done more than he could justifie by law, for if he were a false Prophet, the Judgment of him belonged not to him but to the Sanhedrim. He had nothing to do to smite him, possibly he brought him forth in order to bring him before the Sanhedrim; but it doth not appear that he did so, tho' Ieremiahs following words to him might reasonably be thought provocative enough if he had designed any formal charge against him.

He had it seemeth no more to say to Ieremiah, but Ieremiah (to whom God had appeared in the Prison that night, while he was separated from communion with men, and revealed to him, what end this hot-headed Priest should come to) had something to say to him.

Gods meaning was not that he should by men be no longer called Pashur for doubtless after this he was called by the same name he had before, but his state and condition should not answer the name Pashur, which signifies, as some say, a noble flourishing Priest; or, as others, one who by his Authority maketh others to tremble; but Magor-missabib, that is fear, and terror on all sides.
