Excerpt from the LDS temple marriage ceremony (sealing of spouses). [footnote]The LDS Endowment, Sealings [/footnote]

[The sealer sits at the head of the altar with two witnesses, one seated at his right and the other at his left. The bride and groom kneel at opposite sides of the altar, facing one another, clothed in the robes of the holy priesthood. They take each other by the right hand in the patriarchal grip.]

SEALER: Brother _________, do you take Sister _________ by the right hand and receive her unto yourself to be your lawfully wedded wife, for time and all eternity, with a covenant and promise that you will observe and keep all the laws, rites, and ordinances pertaining to this holy order of matrimony in the new and everlasting covenant; and this you do in the presence of God, angels, and these witnesses of your own free will and choice?

GROOM: Yes.

SEALER: Sister _________, do you take Brother _________ by the right hand and give yourself to him to be his lawfully wedded wife, and receive him to be your lawfully wedded husband, for time and all eternity, with a covenant and promise that you will observe and keep all the laws, rites, and ordinances pertaining to this holy order of matrimony in the new and everlasting covenant; and this you do in the presence of God, angels, and these witnesses of your own free will and choice?

BRIDE: Yes.

SEALER: By virtue of the holy priesthood and the authority vested in me, I pronounce you, _________ and _________, legally and lawfully husband and wife for time and all eternity; and I seal upon you the blessings of the holy resurrection, with power to come forth in the morning of the first resurrection, clothed in glory, immortality, and eternal lives.
I seal upon you the blessings of kingdoms, thrones, principalities, powers, dominions, and exaltations, with all the blessings of Abraham, Isaac, and Jacob; and say unto you: be fruitful and multiply and replenish the earth, that you may have joy and rejoicing in the day of our Lord Jesus Christ.

All these blessings, together with all the blessings appertaining unto the new and everlasting covenant, I seal upon you by virtue of the holy priesthood, through your faithfulness, in the name of the Father, and of the Son, and of the Holy Ghost. Amen.
