'Insane' in the Bible

So [fearing for his life] he changed his behavior in their sight, and acted insanely in their hands, and he scribbled on the doors of the gate, and drooled on his beard.

The Jews said to Him, “Now we know that You have a demon [and are under its power]. Abraham died, and also the prophets; yet You say, ‘If anyone keeps My word, he will never, ever taste of death.’

Many of them said, “He has a demon and He is mad [insane—He raves and rambles]. Why listen to Him?”

While Paul was making this defense, Festus said loudly, “Paul, you are out of your mind! Your great education is turning you toward madness.”
