ויישם [וַיּוּשַׂ֤ם] לְפָנָיו֙ לֶאֱכֹ֔ל וַיֹּ֙אמֶר֙ לֹ֣א אֹכַ֔ל עַ֥ד אִם־דִּבַּ֖רְתִּי דְּבָרָ֑י וַיֹּ֖אמֶר דַּבֵּֽר׃
און עס איז געשטעלט געװאָרן פֿאַר אים צום עסן, אָבער ער האָט געזאָגט: איך װעל ניט עסן, ביז איך האָב גערעדט מײַנע רײד. האָט ער געזאָגט: רעד.

Genesis 24,33. “I will not eat until after I have said what I have come here to say.” Eliezer betrothed Rivkah in his capacity as Yitzchok’s representative. It is a rule that on the day of his wedding, the groom is not allowed to eat until after he has wed the bride. [Nowadays both groom and bride fast until after the ceremony. Ed.]
