Jeremiah 37:19 - Matthew Poole's English Annotations on the Holy Bible

You now see what kind of prophets they are, who fed you with hopes that the king of Babylon's army should return no more to the siege of the city. I told you they would return, you had other prophets that told you they should not, judge now who were the true prophets. The devil in all ages had some that contradicted the true prophets of the Lord. Three hundred false prophets contradicted one Micaiah, as to Ahab's going up to Ramoth-gilead, and prospering in that expedition. There were many that contradicted Isaiah and Jeremiah, and other true prophets, as to the king of Babylon's coming to besiege Jerusalem, and his return again to the siege when he had risen up from it to meet the Egyptian army; and as to the length of time in which the Jews should be in captivity; yet, (to let us see men's madness upon their lusts,) as there still have risen up in other generations false teachers and flatterers, so they have always found more favour than those that have dealt more faithfully in revealing God's will.
