Yasis alayich elokaich, k'msos chatan al kalah
ישיש עליך אלוקיך כמשוש חתן על כלה
Thy God shall rejoice over thee, as a bridegroom rejoiceth over his bride.
Translation from The Standard Prayer book by Simeon Singer (1915) (public domain)
Excerpt from the kabbalat Shabbat song 'Lechah Dodi', which, because of its reference to the bride and groom, is commonly sung at weddings, engagements, and sheva berachot.
