1 Samuel 17:33-35

New Revised Standard Version, Anglicised Catholic Edition

³³ Saul said to David, ‘You are not able to go against this Philistine to fight with him; for you are just a boy, and he has been a warrior from his youth.’ ³⁴ But David said to Saul, ‘Your servant used to keep sheep for his father; and whenever a lion or a bear came, and took a lamb from the flock, ³⁵ I went after it and struck it down, rescuing the lamb from its mouth; and if it turned against me, I would catch it by the jaw, strike it down, and kill it.
