To wit, Christ, the Angel of the covenant, as may be gathered both from the following words, because pardon of sin, which is God's prerogative, Mark 2:7, is here ascribed to him, and God's name is in him, and by comparing other scriptures, as Exodus 32:34 Acts 7:38,39 1 Corinthians 10:9. See Exodus 13:21, Exodus 14:19.
