Mosiah 18:13

And when he had said these words, the Spirit ^a of the Lord was upon him, and he said: Helam, I baptize thee, having authority ^b from the Almighty God, as a testimony that ye have entered into a covenant ^c to serve him until you are dead as to the mortal body; and may the Spirit of the Lord be poured out upon you; and may he grant unto you eternal life, through the redemption of Christ, whom he has prepared from the foundation ^d of the world.
