They have testified of Christ

Moses had such great
power given unto him,
yea, the words which
he hath spoken
concerning the coming
of the Messiah.

Yea, did he not
bear record that
the Son of God
should come?

And as he lifted up
the brazen serpent
in the wilderness,
even so shall he
be lifted up
who should come.

And as many as
should look upon
that serpent
should live,
even so as many
as should look upon
the Son of God with faith,
having a contrite spirit,
might live, even unto
that life which is eternal.

And now behold,
Moses did not only
testify of these things,
but also all the holy prophets
and also almost all of our fathers,
even down to this time;
yea, they have testified
of the coming of Christ,
and have looked forward,
and have rejoiced in
his day which is to come.

And behold, he is God,
and he is with them,
and he did manifest
himself unto them,
that they were
redeemed by him;
and they gave
unto him glory.
