1 Samuel 30:8-9 KJV
And David enquired at the LORD, saying, Shall I pursue after this troop? shall I overtake them? And he answered him, Pursue: for thou shalt surely overtake them, and without fail recover all. So David went, he and the six hundred men that were with him, and came to the brook Besor, where those that were left behind stayed.
