1 Samuel 30:9-10; 1 Samuel 30:21

9 David and the six hundred men with him came to the Besor Valley, where some stayed behind. 10 Two hundred of them were too exhausted to cross the valley, but David and the other four hundred continued the pursuit.
21 Then David came to the two hundred men who had been too exhausted to follow him and who were left behind at the Besor Valley. They came out to meet David and the men with him. As David and his men approached, he asked them how they were.
