ספר בראשית

Another way of understanding Eliezer’s refusal ‎to eat before he had acquainted his host with his mission, is that ‎the very meal would be converted into a ‎סעודת מצוה‎, a festive ‎meal of religious significance, once he had betrothed Rivkah. [I ‎find this difficult, as Eliezer is described as eating and drinking in ‎verse 54 before Rivkah had been asked if she accepted the ‎proposal and was willing to go to Kiryat Arba. Ed.]‎
