(15) By God.--The oath was to be by "Elohim," not by Jehovah, of whom the Egyptian knew nothing.

And I will bring thee down.--His accurate knowledge of the route taken by the Amalekites, and his clear account of the late raid, show that he was a person of no ordinary ability; he was probably an Egyptian merchant or wealthy trader captured in some border fray.

Verse 15. - To this company. Better, "troop." The word signifies a band of soldiers, robbers, or the like. Required by David to act as his guide, the Egyptian consents upon condition that David bind himself neither to kill him, it being one of the unscrupulous customs of ancient warfare to put deserters, persons forced to act as guides, and even noncombatants, to death to save trouble; nor give him up to his master, who would treat him in the same way.

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 said unto him, canst thou me down to this company?.... That is, show him, or direct him where they were:

and he said, swear unto me by God; the Targum is, by the Word of the Lord; but it is highly probable this man had no notion of Jehovah, and his Word, or of the true God; only that there was a God, and that an oath taken by him was solemn, sacred, and inviolable, and might be trusted to and depended on:

that thou wilt neither kill me; for he found now he was in the hands of those whose city he had been concerned in plundering and burning, and so might fear his life was in danger:

nor deliver me into the hands of my master; who had been a cruel one to him, and therefore would gladly be clear of him; and if he had nothing else against him, his late usage of him was sufficient to raise his resentment of him:

and I will bring thee down to this company; or show him where they were, having heard them say where they would stop, and make merry, and divide their spoil; and perhaps his master might tell him they would be at such a place at such a time, where, if he was better, he might come to them; the Vulgate Latin version adds, "and David swore to him": which, though not expressed in the original text, was no doubt done by him; and the Syriac and Arabic versions begin 1 Samuel 30:16 thus, "when David had sworn to him".
