for it is He who shall save His people from their sins

"But when he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, 'Joseph, son of David, don’t be afraid to take to yourself Mary, your wife, for that which is conceived in her is of the Holy Spirit. She shall bring forth a son. You shall call his name Jesus, for it is he who shall save his people from their sins.'" -Matthew 1:20-21 (WEB)
