1 Samuel 30:7-8

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. 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.
