1 Samuel 30:3-4, 6, 9-10

And when David and his men came to the city, they found it burned with fire, and their wives and sons and daughters taken captive. Then David and the people who were with him raised their voices and wept until they had no more strength to weep.

And David was greatly distressed, for the people spoke of stoning him, because all the people were bitter in soul, each for his sons and daughters. But David strengthened himself in the LORD his God.

So David set out, and the six hundred men who were with him, and they came to the brook Besor, where those who were left behind stayed. But David pursued, he and four hundred men. Two hundred stayed behind, who were too exhausted to cross the brook Besor.
