1 Samuel 30:9 ASV

⁷  And David said to Abiathar the priest, the son of Ahimelech, I pray thee, bring me hither the ephod. And Abiathar brought thither the ephod to David.

⁸  And David inquired of Jehovah, saying, If I pursue after this troop, shall I overtake them? And he answered him, Pursue; for thou shalt surely overtake `them', and shalt without fail recover `all'.

⁹  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.

¹⁰  But David pursued, he and four hundred men; for two hundred stayed behind, who were so faint that they could not go over the brook Besor.

¹¹  And they found an Egyptian in the field, and brought him to David, and gave him bread, and he did eat; and they gave him water to drink.
