Bible: 1 Samuel 30:8, 10, 17

30:8 David inquired of the Lord, saying, “Should I pursue this raiding band? Will I overtake them?” He said to him, “Pursue, for you will certainly overtake them and carry out a rescue!

30:10 David and four hundred men continued the pursuit, but two hundred men who were too exhausted to cross the Wadi Besor stayed there.

30:17 But David struck them down from twilight until the following evening. None of them escaped, with the exception of four hundred young men who got away on camels. 1
