Deuteronomy 22:13

And Jacob said unto Laban, Give me my wife, for my days are fulfilled, that I may go in unto her.

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 when the LORD saw that Leah was hated, he opened her womb: but Rachel was barren.

When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
