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.But David pursued, he and four hundred men,.... Not discouraged with being obliged to leave a third part of his little army behind; though it was doubtless a trial of his faith, with these to pursue an enemy, whose numbers he knew not, which must greatly exceed his; for after the rout and slaughter of them, as many escaped on camels as David had with him, 1 Samuel 30:17,

for two hundred abode behind, which were so faint; through their grief and sorrow for the loss of their wives and children, and through their march from the camp of the Philistines to Ziklag, and from thence hither, that they looked like a corpse, as the word signifies; Procopius Gazaeus has it only seventy men:

so that they could not go over the brook Besor: being so weak and feeble; for this was not owing to fear of their enemies, and faint heartedness on that account, then it would rather have been said, "they would not go over"; the Targum renders the word "faint" by "restrained" or prohibited, as if they were forbid by David to go over, but were ordered to tarry here by the stuff, while the rest pursued; and, according to the Syriac and Arabic versions, they were placed there, that none might go over the brook; and it seems, by 1 Samuel 30:22, that they had a good will to go over, but were made to abide there; or as all Gideon's army, but three hundred, were sent back, and not suffered to go with him, being too many, Judges 7:2.
