Thematic Bible: Kills a lion and a bear

David said to Saul, "Your servant was keeping his father's sheep; and when a lion or a bear came, and took a lamb out of the flock, I went out after him, and struck him, and rescued it out of his mouth. When he arose against me, I caught him by his beard, and struck him, and killed him. Your servant struck both the lion and the bear, and this uncircumcised Philistine shall be as one of them [Should I not go and smite him, and remove this day a reproach from Israel? For who is this uncircumcised one], since he has defied the armies of the living God?"
