221 David therefore departed there, and escaped to the cave of Adullam. When his brothers and all his father’s house heard it, they went down there to him. 2 Everyone who was in distress, and everyone who was in debt, and everyone who was discontented, gathered themselves to him; and he became captain over them: and there were with him about four hundred men. 3 David went there to Mizpeh of Moab, and he said to the king of Moab, “Please let my father and my mother come out with you, until I know what God will do for me.” 4 He brought them before the king of Moab; and they lived with him all the while that David was in the stronghold.

(Read 1 Samuel 22:1-5)
See what weak instruments God sometimes uses, to bring about his own purposes. The Son of David is ready to receive distressed souls, who will be commanded by him. He receives all who come unto Him, however vile and miserable; he changes them into a holy people, and employs them in his service: those who would reign with him must be contented first to suffer with and for him. Observe with what tender concern David provided for his aged parents. The first thing he does is to find them a quiet habitation, whatever became of himself. Let children learn to honour their parents, in every thing consulting their ease and satisfaction. Though highly preferred, and much employed, let them not forget their aged parents. The steps of a good man are ordered by the Lord. And the Lord will preserve his people for their appointed work, however they may be hated and exposed.
