1 Samuel 21
10 Ref David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.
11 Ref The servants of Achish said to him, "Isn't this David the king of the land? Didn't they sing one to another about him in dances, saying, 'Saul has slain his thousands, David his ten thousands?'"
12 Ref David laid up these words in his heart, and was very afraid of Achish the king of Gath.
13 Ref He changed his behavior before them, and feigned himself mad in their hands, and scrabbled on the doors of the gate, and let his spittle fall down on his beard.
14 Ref Then said Achish to his servants, Look, you see the man is mad; why then have you brought him to me?
15 Do I lack madmen, that you have brought this fellow to play the madman in my presence? shall this fellow come into my house?
