Genesis 29:18, 20, 30-31, 33

And Jacob loved Rachel; and said, I will serve thee seven years for Rachel thy younger daughter.

And Jacob served seven years for Rachel; and they seemed unto him but a few days, for the love he had to her.

And he went in also unto Rachel, and he loved also Rachel more than Leah, and served with him yet seven other years. And when the LORD saw that Leah was hated, he opened her womb: but Rachel was barren.

And she conceived again, and bare a son; and said, Because the LORD hath heard that I was hated, he hath therefore given me this son also: and she called his name Simeon.
