And David inquired of the Lord
 That is, by Abiathar, who reported his questions to the Lord in his name: 
 saying, shall I pursue after this troop?
 the large company of the Amalekites, as it appears by what follows they were: 
 shall I overtake them?
 two questions are here put together, and answers returned to them, contrary to a notion of the Jews; (See Gill on  1 Samuel 23:11); 
 and he answered him, pursue;
 which respects the first question: 
 for thou shall surely overtake [them];
 which is an answer to the second question, and a full one, giving full assurance of overtaking; to which is added more than what was inquired about; 
 and without fail recover [all];
 their wives, sons, and daughters, and the spoil that was taken; or "in delivering thou shall deliver" F16, out of the hands of the Amalekites, whatsoever they had taken.
