1 Samuel 30:7-9

Amplified Bible

⁷ David said to Abiathar the priest, Ahimelech’s son, “Please bring me the ephod.” So Abiathar brought him the ephod. ⁸ David inquired of the Lord, saying, “Shall I pursue this band [of raiders]? Will I overtake them?” And He answered him, “Pursue, for you will certainly overtake them, and you will certainly rescue [the captives].” ⁹ So David went, he and the six hundred men who were with him, and came to the brook Besor; there those [who could not continue] remained behind.
