John Gill Commentary Genesis 29:30

"And he went in also unto Rachel, and he loved also Rachel more than Leah, and served with him yet seven other years." — Genesis 29:30 (ASV)

And he went in also unto Rachel
Cohabited with her as his wife:

and he loved also Rachel more than Leah ;
she was his first love, and he retained the same love for her he ever had; as appears by his willingness to agree to the same condition of seven years' servitude more for her sake, and which he performed as follows:

and served with him, yet seven other years ;
that is, Jacob served so many years with Laban after he had married his two daughters, and fulfilled the weeks of feasting for each of them.
