Jeremiah 20:3 - Matthew Poole's English Annotations on the Holy Bible

Possibly by this time the mad-brained priest thought he had done more than he could justify 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 his bringing him before the sanhedrim; but it doth not appear that he did so, though Jeremiah's 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 Jeremiah, but Jeremiah (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. God's 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.
