2 Chronicles 18:13-15

But Micaiah said, “As the LORD lives, what my God says, that I will speak.” And when he had come to the king, the king said to him, “Micaiah, shall we go to Ramoth-gilead to battle, or shall I refrain?” And he answered, “Go up and triumph; they will be given into your hand.” But the king said to him, “How many times shall I make you swear that you speak to me nothing but the truth in the name of the LORD?”
