Deuteronomy 24:1–4

Laws Concerning Divorce

[1] “When a man takes a wife and marries her, if then she finds no favor in his eyes because he has found some indecency in her, and he writes her a certificate of divorce and puts it in her hand and sends her out of his house, and she departs out of his house, [2] and if she goes and becomes another man’s wife, [3] and the latter man hates her and writes her a certificate of divorce and puts it in her hand and sends her out of his house, or if the latter man dies, who took her to be his wife, [4] then her former husband, who sent her away, may not take her again to be his wife, after she has been defiled, for that is an abomination before the LORD. And you shall not bring sin upon the land that the LORD your God is giving you for an inheritance. (ESV)

Matthew 19:3–9

[3] And Pharisees came up to him and tested him by asking, “Is it lawful to divorce one’s wife for any cause?” [4] He answered, “Have you not read that he who created them from the beginning made them male and female, [5] and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? [6] So they are no longer two but one flesh. What therefore God has joined together, let not man separate.” [7] They said to him, “Why then did Moses command one to give a certificate of divorce and to send her away?” [8] He said to them, “Because of your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. [9] And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.” (ESV)

Matthew 5:27–32

Lust

[27] “You have heard that it was said, ‘You shall not commit adultery.’ [28] But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart. [29] If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell. [30] And if your right hand causes you to sin, cut it off and throw it away. For it is better that you lose one of your members than that your whole body go into hell.

Divorce

[31] “It was also said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ [32] But I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery. (ESV)
