Thematic Bible: David in feigning madness

And he changed his countenance before them, and raved in their hands, and scrabbled on the doors of the gate, and let his spittle fall down upon his beard. Then said Achish unto his servant, "Lo, ye saw that this man was beside himself; wherefore then have ye brought him to me? Lack I madmen, that ye have brought this fellow to play the madman in my presence? He shall not come into my house."
