1 Samuel 21:13

13So he pretended to be insane in their presence; and while he was in their hands he acted like a madman, making marks on the doors of the gate and letting saliva run down his beard.

13So he disguised his sanity before them, and acted insanely in their hands, and scribbled on the doors of the gate, and let his saliva run down into his beard.

13So he changed his behavior before them and feigned madness in their hands; he scratched on the doors of the gate and let his saliva run down his beard.

13So he pretended to be out of his mind when he was with them. As long as he was in Gath, he acted like a crazy person. He made marks on the doors of the city gate. He let spit run down his beard.
