Alma 3

And these are the words which he spake to the people in the church which were established in the city of Zarahemla, according to his own record, saying, I, Alma, having been consecrated by my father Alma to be a high priest over the church of God — he having power and authority from God to do these things — behold, I say unto you that he began to establish a church in the land which was in the borders of Nephi — yea, the land was called the land of Mormon — yea, and he did baptize his brethren in the waters of Mormon. And behold, I say unto you, they were delivered out of the hands of the people of king Noah by the mercy and power of God.
