Commento su Genesi 29:22

ויאסוף לבן....ויעש משתה, Lavan assembled the people from Charan and arranged a feast. Lavan was a swindler, and that is why he is always referred to by our sages as “Lavan the swindler.” He planned to make Yaakov drunk in order to deceive him so that he could not tell the difference between Rachel and Leah. If we needed proof for this interpretation, we only need to look at when he gave Rachel to Yaakov a week later, when he did not spend a penny on making a celebration.
