1 Samuel 21:11-15

AKJV(i) 11 And the servants of Achish said to him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul has slain his thousands, and David his ten thousands? 12 And David laid up these words in his heart, and was sore afraid of Achish the king of Gath. 13 And 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 Then said Achish to his servants, See, you see the man is mad: why then have you brought him to me? 15 Have I need of mad men, that you have brought this fellow to play the mad man in my presence? shall this fellow come into my house?
