'Inquired of the Lord' in the Bible

Then it came about afterwards that David inquired of the Lord, saying, “Shall I go up to one of the cities of Judah?” And the Lord said to him, “Go up.” So David said, “Where shall I go up?” And He said, “To Hebron.”

Then David inquired of the Lord, saying, “Shall I go up against the Philistines? Will You give them into my hand?” And the Lord said to David, “Go up, for I will certainly give the Philistines into your hand.”

When David inquired of the Lord, He said, “You shall not go directly up; circle around behind them and come at them in front of the balsam trees.
