David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.
And David took these words to heart, and was much afraid of Achish the king of Gath.  So he changed his behavior before them, and feigned himself mad in their hand, and made marks on the doors of the gate, and let his spittle run down his beard.  Then said Achish to his servants, "Lo, you see the man is mad; why then have you brought him to me?  Do I lack madmen, that you have brought this fellow to play the madman in my presence?  Shall this fellow come into my house"?"
