1 Samuel 30:6-8

David was greatly distressed, for the men spoke of stoning him because the souls of them all were bitterly grieved, each man for his sons and daughters. But David encouraged and strengthened himself in the Lord his God. David said to Abiathar the priest, Ahimelech's son, I pray you, bring me the ephod. And Abiathar brought him the ephod. And David inquired of the Lord, saying, Shall I pursue this troop? Shall I overtake them? The Lord answered him, Pursue, for you shall surely overtake them and without fail recover all.
