1 Samuel 30:1-9

And it came to pass, when David and his men were come to Ziklag on the third day, that the Amalekites had made a raid upon the South, and upon Ziklag, and had smitten Ziklag, and burned it with fire, and had taken captive the women and all that were therein, both small and great: they slew not any, but carried them off, and went their way. And when David and his men came to the city, behold, it was burned with fire; and their wives, and their sons, and their daughters, were taken captive. 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. So David went, he and the six hundred men that were with him, and came to the brook Besor, where those that were left behind stayed.
