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

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.
