Deuteronomy 24:1

24:1 If a man marries a woman and she does not please him because he has found something offensive in her, then he may draw up a divorce document, give it to her, and evict her from his house.

Isaiah 50:1

50:1 This is what the Lord says:

“Where is your mother’s divorce certificate

by which I divorced her?

Or to which of my creditors did I sell you?

Look, you were sold because of your sins;

because of your rebellious acts I divorced your mother.
