11 And the servants of Achish said to him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul has smitten his thousands, and David his ten thousands?

Matthew Henry's Commentary on 1 Samuel 21:11

Commentary on 1 Samuel 21:10-15

(Read 1 Samuel 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.
