1 Samuel 21:13-15
Context21:13 He altered his behavior in their presence. 1 Since he was in their power, 2 he pretended to be insane, making marks on the doors of the gate and letting his saliva run down his beard.
21:14 Achish said to his servants, “Look at this madman! Why did you bring him to me? 21:15 Do I have a shortage of fools, that you have brought me this man to display his insanity in front of me? Should this man enter my house?”
