1 Samuel 30:8-10

New Century Version

⁸ Then David asked the Lord, “Should I chase the people who took our families? Will I catch them?”

The Lord answered, “Chase them. You will catch them, and you will succeed in saving your families.”

⁹ David and the six hundred men with him came to the Besor Ravine, where some of the men stayed. ¹⁰ David and four hundred men kept up the chase. The other two hundred men stayed behind because they were too tired to cross the ravine.
