2 Samuel 5:19

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, 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.
