21:13 And he changed his behaviour before them, and feigned himself mad in their hands, and {i} scrabbled on the doors of the gate, and let his spittle fall down upon his beard.
(i) By making marks and toys.
21:10-15 God's persecuted people have often found better usage from Philistines than from Israelites. David had reason to put confidence in Achish, yet he began to be afraid. His conduct was degrading, and discovered wavering in his faith and courage. The more simply we depend on God, and obey him, the more comfortably and surely we shall walk through this troublesome world.
