1 Samuel 30:6-8

6Further, David was greatly distressed because the people spoke of stoning him, for all of them were embittered, each man for his sons and daughters. But David felt strengthened and encouraged in the Lord his God.

7David said to Abiathar the priest, Ahimelech’s son, “Please bring me the ephod.” So Abiathar brought him the ephod.

8David 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].”
