Deuteronomy 24:1-4

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. 24:2 When she has left him she may go and become someone else’s wife. 24:3 If the second husband rejects her and then divorces her, gives her the papers, and evicts her from his house, or if the second husband who married her dies, 24:4 her first husband who divorced her is not permitted to remarry her after she has become ritually impure, for that is offensive to the Lord. You must not bring guilt on the land which the Lord your God is giving you as an inheritance.

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.

Matthew 5:31-32

Divorce

5:31 “It was said, ‘Whoever divorces his wife must give her a legal document.’ 5:32 But I say to you that everyone who divorces his wife, except for immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery.

Matthew 19:3-9

19:3 Then some Pharisees came to him in order to test him. They asked, “Is it lawful to divorce a wife for any cause?” 19:4 He answered, “Have you not read that from the beginning the Creator made them male and female, 19:5 and said, ‘For this reason a man will leave his father and mother and will be united with his wife, and the two will become one flesh’? 19:6 So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.” 19:7 They said to him, “Why then did Moses command us to give a certificate of dismissal and to divorce her?” 19:8 Jesus said to them, “Moses permitted you to divorce your wives because of your hard hearts, but from the beginning it was not this way. 19:9 Now I say to you that whoever divorces his wife, except for immorality, and marries another commits adultery.”

Mark 10:2-12

10:2 Then some Pharisees came, and to test him they asked, “Is it lawful for a man to divorce his wife?” 10:3 He answered them, “What did Moses command you?” 10:4 They said, “Moses permitted a man to write a certificate of dismissal and to divorce her.” 10:5 But Jesus said to them, “He wrote this commandment for you because of your hard hearts. 10:6 But from the beginning of creation he made them male and female. 10:7 For this reason a man will leave his father and mother, 10:8 and the two will become one flesh. So they are no longer two, but one flesh. 10:9 Therefore what God has joined together, let no one separate.”

10:10 In the house once again, the disciples asked him about this. 10:11 So he told them, “Whoever divorces his wife and marries another commits adultery against her. 10:12 And if she divorces her husband and marries another, she commits adultery.”

Luke 16:18
