Deuteronomy 24:1

“If a man marries a woman, but she becomes displeasing to him because he finds some indecency in her, he may write her a certificate of divorce, hand it to her, and send her away from his house.”

“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.”

“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.”
