1 Samuel 17:34-37

34David replied, “Your servant has been tending his father’s sheep, and whenever a lion or a bear came and carried off a lamb from the flock, 35I went after it, struck it down, and delivered the lamb from its mouth. If it reared up against me, I would grab it by its fur, strike it down, and kill it. 36Your servant has killed lions and bears; this uncircumcised Philistine will be like one of them, for he has defied the armies of the living God.”

37David added, “The LORD, who delivered me from the claws of the lion and the bear, will deliver me from the hand of this Philistine.”

“Go,” said Saul, “and may the LORD be with you.”
