Book of Common Prayer (page 434)

The Celebrant then addresses the congregation, saying

Will you who have witnessed these promises do all in your
power to uphold these two persons in their marriage?

People We will.

If a ring or rings are to be blessed, the wife extends her hand (and
the husband extends his hand) toward the Priest, who says

Bless, O Lord, this ring to be a sign of the vows by which
this man and this woman have bound themselves to each
other; through Jesus Christ our Lord. Amen.

The Celebrant joins the right hands of the husband and wife and says
Those whom God has joined together let no one put asunder.

The Congregation responds Amen.
