1 Samuel 21:13-15

World English Bible

¹³ He changed his behavior before them, and pretended to be insane in their hands, and scribbled on the doors of the gate, and let his spittle fall down on his beard. ¹⁴ Then Achish said to his servants, “Look, you see the man is insane. 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? Should this fellow come into my house?”
