1 Samuel 30:7-8

Then David said to Abiathar the priest, the son of Ahimelech, “Please bring me the ephod.” So Abiathar brought the ephod to David. David inquired of the LORD, saying, “Shall I pursue this band? Shall I overtake them?” And He said to him, “Pursue, for you will surely overtake them, and you will surely rescue all.”
