Sealed book of Mormon Ch.38

AND now, in everything that John did, he
prepared the people for the ministry of Christ.
For there began to be many among them who
believed on the words of John, because they
accepted him as a prophet of God.
But the leaders of the church, and also
many of the members of the church who had
placed their trust in their leaders, did not
believe that John was a prophet of God, but
that he said these things of himself, having
alienated himself from the church because of
his disagreements with his father who was a
high priest of the church.
And Zacharias had known of the calling of
John since his conception. Nevertheless, he
had convinced himself that John would one
day be a great high priest in the church, in
which he would prepare the people for the
coming of the Messiah, upon whom the
church waited for their salvation.
For upon his birth, Zacharias regained his
ability to speak, and he prophesied that which
the Spirit gave unto him, saying, Blessed be the
Lord God of Israel; for he hath visited and
redeemed his people, and hath raised up an horn
of salvation for us in the house of David, as he
spake by the mouth of his holy prophets, which
have been since the world began; that we should
be saved from our enemies, and from the hand
of all that hate us; to perform the mercy
promised to our fathers, and to remember his
holy covenant, even the oath which he sware to
our father Abraham, that he would grant unto us
that we, being delivered out of the hand of our
enemies, might serve him without fear, in
holiness and righteousness before him, all the
days of our life.
