My master left me, because three days agone I fell sick - This was very inhuman: though they had booty enough, and no doubt asses sufficient to carry the invalids, yet they left this poor man to perish; and God visited it upon them, as he made this very person the means of their destruction, by the information which he was enabled to give to David and his men.

And David said unto him, to whom belongest thou?.... To what country or people? and to whom among them?

and whence art thou? of what nation? where wast thou born? what countryman art thou? for his being called an Egyptian before seems to be by anticipation, unless it was guessed at by his habit; for until he had eaten and drank he could not speak, and so could not be known by his speech:

for he said, I am a young man of Egypt; that was the country he belonged to, and came from; he was an Egyptian by birth:

servant to an Amalekite; one of those that had invaded the country, and burnt Ziklag, as it follows:

and my master left me, because three days agone I fell sick; which was very barbarous and cruel to leave him at all, when they had camels with them, 1 Samuel 30:17; and no doubt carriages for their arms, provision, and spoil, and men; and more so to leave him without anybody with him to take care of him, and without any food, when he capable of eating any; but so it was ordered by the providence of God, that should be left to be the instrument of the just ruin of his master, and of the whole troop.

When David asked him whence he had come (to whom, i.e., to what people or tribe, dost thou belong?), the young man said that he was an Egyptian, and servant of an Amalekite, and that he had been left behind by his master when he fell sick three days before ("to-day three," sc., days): he also said, "We invaded the south of the Crethites, and what belongs to Judah, and the south of Caleb, and burned Ziklag with fire." הכּרתי, identical with כּרתים (Ezekiel 25:16; Zephaniah 2:5), denotes those tribes of the Philistines who dwelt in the south-west of Canaan, and is used by Ezekiel and Zephaniah as synonymous with Philistim. The origin of the name is involved in obscurity, as the explanation which prevailed for a time, viz., that it was derived from Creta, is without sufficient foundation (vid., Stark, Gaza, pp. 66 and 99ff.). The Negeb "belonging to Judah" is the eastern portion of the Negeb. One part of it belonged to the family of Caleb, and was called Caleb's Negeb (vid., 1 Samuel 25:3).

And David said unto him, To whom belongest thou? and whence art thou? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days agone I fell sick.

30:13 Egypt - God by his providence so ordering it, that he was not one of that cursed race of the Amalekites, who were to be utterly destroyed, but an Egyptian, who might be spared. Left me - In this place and condition: which was barbarous inhumanity: for he ought, and easily might have carried him away with the prey which they had taken. But he paid dear for this cruelty, for this was the occasion of the ruin of him and all their company. And God by his secret providence ordered the matter thus for that very end. So that there is no fighting against God, who can make the smallest accidents serviceable to the production of the greatest effects.

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.
