'Insane' in the Bible

until you are driven insane from what your eyes will see.

LORD, may your gracious love be upon us, even as we hope in you. By David, when he pretended to be insane before Abimelech, who drove him away. So David left.

The time for your judgment has now come; payday is here and Israel knows it. The prophet is a fool, and the spiritual man is insane. Because of your great sin, the hatred against you is great.

Many of them were saying, "He has a demon and is insane. Why bother listening to him?"

Are they the Messiah's servants? I am insane to talk like this, but I am a far better one! I have been involved in far greater efforts, far more imprisonments, countless beatings, and have faced death more than once.
