Caesarius of Arles, on 1Sam 17:34

“And David said to Saul: Thy servant kept his father’s sheep, and there came a lion, or a bear, and took a ram out of the midst of the flock:”

“When David had been anointed by blessed Samuel before he came here, he had killed a lion and a bear without any weapons, as he himself told King Saul. Both the lion and the bear typified the devil, for they had been strangled by the strength of David for having dared to attack some of his sheep. All that we read prefigured in David at that time, dearly beloved, we know was accomplished in our Lord Jesus Christ; for he strangled the lion and the bear when he descended into hell to free all the saints from their jaws. Moreover, listen to the prophet entreating the person of our Lord: "Rescue my soul from the sword, my loneliness from the grip of the dog. Save me from the lion's mouth." Since a bear possesses his strength in his paw and a lion has his in his mouth, the same devil is prefigured in those two beasts. Thus, this was said concerning the person of Christ, in order that his sole church might be removed from the hand, that is, the power or mouth of the devil.”
