Yasis alayich elohayich, kimsos chatan al kalah.
יָשִׂישׂ עָלַיִךְ אֱלֹהַיִךְ כִּמְשׂוֹשׂ חָתָן עַל כַּלָּה.
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.
