John Wesley on 1 Samuel 29:4

Make this fellow - Herein the wise and gracious providence of God appeared, both in helping him out of these difficulties, out of which no human wit could have extricated him, but he must have been, an ungrateful person either to the one or the other side, and moreover in giving him the happy opportunity of recovering his own, and his all from the Amalekites, which had been irrecoverably lost, if he had gone into this battle. And the kindness of God to David was the greater, because it had been most just for God to have left David in those distresses into which his own sinful counsel had brought him. These men - That is, of these our soldiers, they speak according to the rules of true policy; for by this very course, great enemies have sometimes been reconciled together.
