I Samuel 30:13

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 (Eze 25:16; Zep 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., Sa1 25:3).

When David was dismissed from the army of the Philistines he did not go over to the camp of Israel, but, being expelled by Saul, observed an exact neutrality, and silently retired to his own city Ziklag, leaving the armies ready to engage. Now here we are told, I. What a melancholy posture he found the city in, all laid waste by the Amalekites, and what distress it occasioned him and his men (Sa1 30:1-6). II. What course he took to recover what he had lost. He enquired of God, and took out a commission from him (Sa1 30:7, Sa1 30:8), pursued the enemy (Sa1 30:9, Sa1 30:10), gained intelligence from a straggler (Sa1 30:11-15), attacked and routed the plunderers (Sa1 30:16, Sa1 30:17), and recovered all that they had carried off (Sa1 30:18-20). III. What method he observed in the distribution of the spoil (Sa1 30:21-31).

30:13 because I was sick: Only healthy and vigorous slaves were valuable to the Amalekites; the rest were expendable.
