to give knowledge of salvation to his people
by the forgiveness of their sins.
77. to give knowledge of salvation—To sound the note of a needed and provided "salvation" was the noble office of John, above all that preceded him; as it is that of all subsequent ministers of Christ; but infinitely loftier was it to be the "Salvation" itself (Lu 1:69 and Lu 2:30).
