Jeremiah
Jeremiah 29:23ASV·traditional attribution

because they have wrought folly in Israel, and have committed adultery with their neighbors’ wives, and have spoken words in my name falsely, which I commanded them not; and I am he that knoweth, and am witness, saith Jehovah.

Geneva Bible Notes Reformed

Because they have committed villany in Israel, and have committed adultery with their neighbour's wives, and have spoken lying words in my name, which I have not commanded them; even I know, and [am] a witness, saith the LORD. (n) Which was adultery and falsifying the word of God.

John Gill Reformed Baptist

These men were impure wretches, unfit to be God's prophets; their adultery and false prophecies alike proved they were sent by no one but themselves. Though their wickedness was hidden from common sight, God saw all their impurity and falsehood, and stands as witness against them.
