Thematic Bible: David feigns madness

And David laid up these words in his heart and was sore afraid of Achish, the king of Gath. read more.
And he changed his behaviour before them and feigned himself a fool in their hands and scrabbled on the doors of the gate and let his spittle fall down upon his beard. Then Achish said unto his slaves, Behold, ye see the man is mad; why then have ye brought him to me? Have I need of mad men that ye have brought this fellow to play the mad man in my presence? Shall this fellow come into my house?
