3 Now turn from the old to the new, from the figure to the reality. There we have Moses sent from God to Egypt; here, Christ, sent forth from His Father into the world: there, that Moses might lead forth an afflicted people out of Egypt; here, that Christ might rescue those who are oppressed in the world under sin: there, the blood of a lamb was the spell against the destroyer; here, the blood of the Lamb without blemish Jesus Christ is made the charm to scare evil spirits: there, the tyrant was pursuing that ancient people even to the sea; and here the daring and shameless spirit, the author of evil, was following you even to the very streams of salvation. The tyrant of old was drowned in the sea; and this present one disappears in the water of salvation.
