Jeremiah 28:11

We must also notice how craftily this impostor insinuated himself; for he seemed to imitate the true prophets of God, for he set a sign before the people, and then added a doctrine. The Papists have their empty signs, but they only delight the eyes, while yet they have no care nor concern for the ears. But Hananiah came still nearer to God’s servants, so that he might deceive even those who were not stupid. What, indeed, could we desire more in this man than that he should set forth a sign? He also added the name of God and declared what was his purpose, in this manner will I break the yoke of Nebuchadnezzar: nor did he speak in his own name, but assumed the person of God, Thus saith Jehovah, I will break the yoke of Nebuchadnezzar.

But as we have elsewhere said, this preposterous imitation of the devil ought not to disturb pious minds; for God ever supplies his own people with the spirit of discernment, provided they humbly pray to him. And therefore whenever Jeremiah repeated the word prophet, which he conceded to Hananiah, as he assumed it himself, for whenever he spoke of Hananiah, he honored him with this name, even that he was a prophet, — the holy man was not ignorant what an occasion of offense it was, when a prophet, who is so acknowledged in the Church of God, is yet the minister of Satan, a liar and an impostor. But his object was to warn us in due time, lest novelty should frighten us when any boasts of the title of a prophet. So the Papists brag that they are prelates and bishops, and boast that they are the successors of the Apostles: but the devil is their chief, who calls himself the Vicar of Christ on the earth. Then Jeremiah designedly called Hananiah so many times a prophet, so that our faith, when any such thing happens to us, may not fail, as though some new thing had taken place. I cannot to-day finish the last part of the verse.
