Y los ojos de Lea eran tiernos, pero Rachêl era de lindo semblante y de hermoso parecer.
Rashi on Genesis
רכות TENDER — She thought she would have to fall to the lot of Esau and she therefore wept continually, because everyone said, “Rebekah has two sons, Laban has two daughters — the elder daughter for the elder son, the younger daughter for the younger son” (Genesis Rabbah 70:16).
Rashbam on Genesis
רכות, beautiful; our sages in Taanit 24 say that when a prospective bride has beautiful eyes, the bridegroom need not have the rest of her body checked out for possible blemishes. Black eyes are not considered as beautiful as white ones. [I suppose the reference is to blue ones. Ed.]
Sforno on Genesis
יפת תאר, possessed of beautiful features, as described in Isaiah 44,13 ובמחוגה יתארהו.
