3 But the Philistine commanders demanded, "What are these Hebrews doing here?" And Achish told them, "This is David, the servant of King Saul of Israel. He's been with me for years, and I've never found a single fault in him from the day he arrived until today."
Matthew Henry's Commentary on 1 Samuel 29:3
Commentary on 1 Samuel 29:1-5
(Read 1 Samuel 29:1-5)
David waited with a secret hope that the Lord would help him out of his difficulty. But he seems to have been influenced too much by the fear of man, in consenting to attend Achish. It is hard to come near to the brink of sin, and not to fall in. God inclined the princes of the Philistines to oppose David's being employed in the battle. Thus their dislike befriended him, when no friend could do him such a kindness.
