2 Samuel 5:19, 23

And David inquired of Jehovah, saying, Shall I go up against the Philistines? wilt thou deliver them into my hand? And Jehovah said unto David, Go up; for I will certainly deliver the Philistines into thy hand.

And when David inquired of Jehovah, he said, Thou shalt not go up: make a circuit behind them, and come upon them over against the mulberry-trees.
