1 Chronicles 14:8-10

King James Version

⁸ And when the Philistines heard that David was anointed king over all Israel, all the Philistines went up to seek David. And David heard of it, and went out against them.

⁹ And the Philistines came and spread themselves in the valley of Rephaim.

¹⁰ And David enquired of God, saying, Shall I go up against the Philistines? And wilt thou deliver them into mine hand? And the Lord said unto him, Go up; for I will deliver them into thine hand.
