7 Then he said to Abiathar the priest, "Bring me the ephod!" So Abiathar brought it. 8 Then David asked the Lord, "Should I chase after this band of raiders? Will I catch them?" And the Lord told him, "Yes, go after them. You will surely recover everything that was taken from you!" 9 So David and his 600 men set out, and they came to the brook Besor. 10 But 200 of the men were too exhausted to cross the brook, so David continued the pursuit with 400 men. 11 Along the way they found an Egyptian man in a field and brought him to David. They gave him some bread to eat and water to drink. 12 They also gave him part of a fig cake and two clusters of raisins, for he hadn't had anything to eat or drink for three days and nights. Before long his strength returned. 13 "To whom do you belong, and where do you come from?" David asked him. "I am an Egyptian-the slave of an Amalekite," he replied. "My master abandoned me three days ago because I was sick. 14 We were on our way back from raiding the Kerethites in the Negev, the territory of Judah, and the land of Caleb, and we had just burned Ziklag." 15 "Will you lead me to this band of raiders?" David asked. The young man replied, "If you take an oath in God's name that you will not kill me or give me back to my master, then I will guide you 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.
