1 Samuel 30:9-12

9So David and his six hundred men went to the Brook of Besor, where some stayed behind 10because two hundred men were too exhausted to cross the brook. But David and four hundred men continued in pursuit.

11Now his men found an Egyptian in the field and brought him to David. They gave the man water to drink and food to eat— 12a piece of a fig cake and two clusters of raisins. So he ate and was revived, for he had not had any food or water for three days and three nights.
