1 Samuel 21:13-15

New King James Version

¹³ So ^(A)he changed his behavior before them, pretended ^[a]madness in their hands, ^[b]scratched on the doors of the gate, and let his saliva fall down on his beard. ¹⁴ Then Achish said to his servants, “Look, you see the man is insane. Why have you brought him to me? ¹⁵ Have I need of madmen, that you have brought this fellow to play the madman in my presence? Shall this fellow come into my house?”
