1 Samuel 30:9-10
9-10David went, he and the six hundred men with him. They arrived at the Brook Besor, where some of them dropped out. David and four hundred men kept up the pursuit, but two hundred of them were too fatigued to cross the Brook Besor, and stayed there.
11-12Some who went on came across an Egyptian in a field and took him to David. They gave him bread and he ate. And he drank some water. They gave him a piece of fig cake and a couple of raisin muffins. Life began to revive in him. He hadn't eaten or drunk a thing for three days and nights!
