1 Samuel 30:4-8

Then David and the people that were with him lifted up their voice and wept, until they had no more power to weep. And David’s two wives were taken captive, Ahinoam the Jezreelitess, and Abigail the wife of Nabal the Carmelite. And David was greatly distressed; for the people spake of stoning him, because the soul of all the people was grieved, every man for his sons and for his daughters: but David strengthened himself in Jehovah his God. And David said to Abiathar the priest, the son of Ahimelech, I pray thee, bring me hither the ephod. And Abiathar brought thither the ephod to David. And David inquired of Jehovah, saying, If I pursue after this troop, shall I overtake them? And he answered him, Pursue; for thou shalt surely overtake them, and shalt without fail recover all.
