7 And David said to Abiathar the priest, the son of Ahimelech, "Bring me the ephod." So Abiathar brought the ephod to David. 8 And David inquired of the Lord, "Shall I pursue after this band? Shall I overtake them?" He answered him, "Pursue, for you shall surely overtake and shall surely rescue." 9 So David set out, and the six hundred men who were with him, and they came to the brook Besor, where those who were left behind stayed. 10 But David pursued, he and four hundred men. Two hundred stayed behind, who were too exhausted to cross the brook Besor. 11 They found an Egyptian in the open country and brought him to David. And they gave him bread and he ate. They gave him water to drink, 12 and they gave him a piece of a cake of figs and two clusters of raisins. And when he had eaten, his spirit revived, for he had not eaten bread or drunk water for three days and three nights. 13 And David said to him, "To whom do you belong? And where are you from?" He said, "I am a young man of Egypt, servant to an Amalekite, and my master left me behind because I fell sick three days ago. 14 We had made a raid against the Negeb of the Cherethites and against that which belongs to Judah and against the Negeb of Caleb, and we burned Ziklag with fire." 15 And David said to him, "Will you take me down to this band?" And he said, "Swear to me by God that you will not kill me or deliver me into the hands of my master, and I will take you down to this band."

Commentary on 1 Samuel 30:7-15

(Read 1 Samuel 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, 2 Corinthians 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.
