1 Samuel 21:13

13 So 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.

33 and blessed be your discernment, and blessed be you, who have kept me this day from bloodshed and from avenging myself by my own hand.
