1 Samuel 17:34-37

34But David said to Saul, “Your servant was tending his father’s sheep. When a lion or a bear came and took a lamb out of the flock,

35I went out after it and attacked it and rescued the lamb from its mouth; and when it rose up against me, I seized it by its whiskers and struck and killed it.

36Your servant has killed both the lion and the bear; and this uncircumcised Philistine will be like one of them, since he has taunted and defied the armies of the living God.”

37David said, “The Lord who rescued me from the paw of the lion and from the paw of the bear, He will rescue me from the hand of this Philistine.” And Saul said to David, “Go, and may the Lord be with you.”
