Wash you, make yourself clean; put away the evil of your doings from before my eyes; cease to do evil;
All Commentaries on Isaiah 1:16 Go To Isaiah 1
Jerome
AD 420
“You are being washed; be clean.” Instead of the sacrifices named above and holocausts and the abundance of fat and the blood of bulls and goats, instead of incense and new moons, the sabbath feast day and fastings, festivals and other solemnities, the religion of the gospel is what pleases me, that you would be baptized in my blood through the washing of regeneration, which alone is able to remove sins. For no one will enter the kingdom of heaven who has not been reborn from water and the spirit. And the Lord himself, ascending to the Father, said, “Go and teach all the nations, baptizing them in the name of the Father, and the Son, and the Holy Spirit.”
