He brought them before ... - The Septuagint renders it "he persuaded (the face of) the king."

In the hold - Where David was after he left the cave of Adullam, probably in the land of Moab.

The phrase "all the while," would indicate that David sojourned a considerable time in Moab.

And he brought them before the king of Moab,.... Having leave from him for it, and left them with him; so the Targum,"caused them to remain before him:"

and they dwelt with him all the whole time that David was in the hold; either in the cave of Adullam, as some think; or rather at Mizpeh in Moab, which might be a fortified place; or the sense may be, while he was in any hold in those parts, as he might go from one to another; what became of David's parents afterwards, we nowhere else read. The Jews (z) say the king of Moab slew his father and his mother, and his brethren, all but one, whom Nahash the Ammonite preserved; and is the kindness David speaks of, 2 Samuel 10:2; and if this was the case, now it was that his father and mother forsook him, and God took him up, Psalm 27:10.

(z) Bemnidbar Rabba, sect. 14. fol. 212. 1. Tanchuma apud Jarchium in loc.

And he {c} brought them before the king of Moab: and they dwelt with him all the while that David was in {d} the hold.

(c) For he feared the rage of Saul against his house.

(d) That is, in Mizpeh, which was a stronghold.

22:4 Hold - In holds; the singular number being put for the plural; as is frequent; that is, as long as David was forced to go from place to place, and from hold to hold, to secure himself: for it concerned David to secure his father, and he did doubtless secure him for all that time; and not only while he was in the hold of Mizpeh, or of Adullam, which was but a little while.

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.
