what is the romantic phrase often used at weddings in "The Tempes"

I can only think of a couple of quotes from Act 3 Scene 1 that might be what you are thinking of. Ferrdinand and Miranda are together in that scene--Miranda says "I would not wish any companion in the world but you". Later Ferdinand says "Hear my soul speak; the very instant that I saw you, did my heart fly at your service." Those quotes are sometimes associated with Valentines Day--not sure about weddings..
