Deuteronomy 24:1 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.

Jeremiah 3:1 THEY say, If a man put away his wife, and she go from him, and become another man's, shall he return unto her again? shall not that land be greatly polluted? but thou hast played the harlot with many lovers; yet return again to me, saith the LORD.

Matthew 5:31 It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement:

Matthew 19:7 They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away?
