30:7-15 If in all our ways, even when, as in this case, there can be no doubt they are just, we acknowledge God, we may expect that he will direct our steps, as he did those of David. David, in tenderness to his men, would by no means urge them beyond their strength. The Son of David thus considers the frames of his followers, who are not all alike strong and vigorous in their spiritual pursuits and conflicts; but, where we are weak, there he is kind; nay more, there he is strong, 2Co 12:9,10. A poor Egyptian lad, scarcely alive, is made the means of a great deal of good to David. Justly did Providence make this poor servant, who was basely used by his master, an instrument in the destruction of the Amalekites; for God hears the cry of the oppressed. Those are unworthy the name of true Israelites, who shut up their compassion from persons in distress. We should neither do an injury nor deny a kindness to any man; some time or other it may be in the power of the lowest to return a kindness or an injury.And David inquired of the Lord,.... That is, by Abiathar, who reported his questions to the Lord in his name:

saying, shall I pursue after this troop? the large company of the Amalekites, as it appears by what follows they were:

shall I overtake them? two questions are here put together, and answers returned to them, contrary to a notion of the Jews; See Gill on 1 Samuel 23:11,

and he answered him, pursue; which respects the first question:

for thou shall surely overtake them; which is an answer to the second question, and a full one, giving full assurance of overtaking; to which is added more than what was inquired about:

and without fail recover all; their wives, sons, and daughters, and the spoil that was taken; or "in delivering thou shall deliver" (p), out of the hands of the Amalekites, whatsoever they had taken.
