1 Samuel 30:6-8

6David was now in great danger because all his men were very bitter about losing their sons and daughters, and they began to talk of stoning him. But David found strength in the Lord his God.

7Then he said to Abiathar the priest, “Bring me the ephod!” So Abiathar brought it.

8Then David asked the Lord, “Should I chase after this band of raiders? Will I catch them?” And the Lord told him, “Yes, go after them. You will surely recover everything that was taken from you!”
