John Gill Commentary Genesis 29:17

"And Leah`s eyes were tender. But Rachel was beautiful and well favored." — Genesis 29:17 (ASV)

Leah [was] tender eyed Blear eyed, had a moisture in them, which made them red, and so she was not so agreeable to look at; though Onkelos renders the words, ``the eyes of Leah were beautiful,'' as if her beauty lay in her eyes, and nowhere else;

but Rachel was beautiful and well favoured ; in all parts, in the form of her countenance, in her shape and stature, and in her complexion, her hair black, her flesh white and ruddy, as Ben Melech observes.
