10 David rose and fled that day from Saul; he went to King Achish of Gath. 11 The servants of Achish said to him, "Is this not David the king of the land? Did they not sing to one another of him in dances, "Saul has killed his thousands, and David his ten thousands'?" 12 David took these words to heart and was very much afraid of King Achish of Gath. 13 So he changed his behavior before them; he pretended to be mad when in their presence. He scratched marks on the doors of the gate, and let his spittle run down his beard. 14 Achish said to his servants, "Look, you see the man is mad; why then have you brought him to me? 15 Do I lack madmen, that you have brought this fellow to play the madman in my presence? Shall this fellow come into my house?"

(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.
