1 Samuel 30:12

And they gave him a piece of a cake of figs, and two clusters of raisins: and when he had eaten, his spirit came again to him: for he had eaten no bread, nor drunk any water, three days and three nights.

He had eaten no bread, nor drunk any water, three days and three nights. According to the Oriental mode of reckoning, three consecutive parts of days were counted three days (Jonah 1:17; Matthew 12:40; Matthew 27:63; Mark 8:31). Old and home-born slaves are usually treated with great kindness. But a purchased or captured slave must look to himself; for, if feeble or sick, his master will leave him to perish rather than encumber himself with additional burden. This Egyptian seems to have recently fallen into the hands of an Amalekite; and his master having belonged to the marauding party that had made the attack on Ziklag, he could give useful information as to the course taken by them on their return.
