And David inquired of the Lord
 By Abiathar, and the Urim and Thummim, in the ephod he had on: 
 saying, shall I go up to the Philistines?
 who by this time were gone from the valley to an higher place, to Mount Perazim, as in ( Isaiah 28:21 ) ; 
 wilt thou deliver them into my hand?
 here two questions are put together, and an answer returned to both, contrary to a notion of the Jews, (See Gill on  1 Samuel 23:11); 
 and the Lord said to David, go up, for I will doubtless deliver the
 Philistines into thine hand;
 by which oracle he had both the mind of God that he should go up, and was assured of victory.
