창세기 29:16 해설: Alshekh, Rashbam, Or HaChaim & Radak

The eyes of Leah were tender. They were weak from crying out to Hashem. In the end her tearful prayers overcame all Yaakov’s efforts to marry only Rochel.

וללבן שתי בנות, the Torah interrupted Yaakov’s narrative by telling us that seeing that Lavan had only two daughters and the younger one appealed to Yaakov, he asked her father for her hand in marriage.

וללבן שתי בנות, And Laban had two daughters, etc. The Torah meant to inform us that both daughters were well known, the elder as Leah and the younger as Rachel so that Laban could not pretend afterwards that their names were different. Jacob stipulated that he would serve Laban for his smaller daughter Rachel in order to remove all possible doubt about whom he had in mind. When the Torah described Leah as גדולה, this was not a relative term, but she was tall in her own right not merely by comparison to Rachel, apart from the fact that she may have been a year or two older than her sister. Rachel too was of below average height not only because of her age.
