Genesis 29:28 (KJV)

And it came to pass in the evening, that he took Leah his daughter, and brought her to him; and he went in unto her.

And Laban gave unto his daughter Leah Zilpah his maid for an handmaid.

And it came to pass, that in the morning, behold, it was Leah: and he said to Laban, What is this thou hast done unto me? did not I serve with thee for Rachel? wherefore then hast thou beguiled me?

And Laban said, It must not be so done in our country, to give the younger before the firstborn.

Fulfil her week, and we will give thee this also for the service which thou shalt serve with me yet seven other years.

And Laban gave to Rachel his daughter Bilhah his handmaid to be her maid.

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 Leah conceived, and bare a son, and she called his name Reuben: for she said, Surely the LORD hath looked upon my affliction; now therefore my husband will love me.

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