Deuteronomy 24:1-2

American Standard Version

24 When a man taketh a wife, and marrieth her, then it shall be, if she find no favor in his eyes, because he hath found some unseemly thing in her, that he shall write her a bill of divorcement, and give it in her hand, and send her out of his house. ² And when she is departed out of his house, she may go and be another man’s wife.
