Divorce 

Matthew 19:3-9 — The Pharisees also came to Him, testing Him, and saying to Him, “Is it lawful for a man to divorce his wife for just any reason?” And He answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’ ? So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.” They said to Him, “Why then did Moses command to give a certificate of divorce, and to put her away?” He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so. And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.”

1 Corinthians 7:10-17 — Now to the married I command, yet not I but the Lord: A wife is not to depart from her husband. But even if she does depart, let her remain unmarried or be reconciled to her husband. And a husband is not to divorce his wife. But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her. And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him. For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy. But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases. But God has called us to peace. For how do you know, O wife, whether you will save your husband? Or how do you know, O husband, whether you will save your wife? But as God has distributed to each one, as the Lord has called each one, so let him walk. And so I ordain in all the churches.

1 Corinthians 7:39 — A wife is bound by law as long as her husband lives; but if her husband dies, she is at liberty to be married to whom she wishes, only in the Lord.

Matthew 5:31-32 — “Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.

Deuteronomy 24:1-4 — “When a man takes a wife and marries her, and it happens that she finds no favor in his eyes because he has found some uncleanness in her, and he writes her a certificate of divorce, puts it in her hand, and sends her out of his house, when she has departed from his house, and goes and becomes another man’s wife, if the latter husband detests her and writes her a certificate of divorce, puts it in her hand, and sends her out of his house, or if the latter husband dies who took her as his wife, then her former husband who divorced her must not take her back to be his wife after she has been defiled; for that is an abomination before the Lord, and you shall not bring sin on the land which the Lord your God is giving you as an inheritance.

Mark 10:2-12 — The Pharisees came and asked Him, “Is it lawful for a man to divorce his wife?” testing Him. And He answered and said to them, “What did Moses command you?” They said, “Moses permitted a man to write a certificate of divorce, and to dismiss her.” And Jesus answered and said to them, “Because of the hardness of your heart he wrote you this precept. But from the beginning of the creation, God ‘made them male and female.’ ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’; so then they are no longer two, but one flesh. Therefore what God has joined together, let not man separate.” In the house His disciples also asked Him again about the same matter. So He said to them, “Whoever divorces his wife and marries another commits adultery against her. And if a woman divorces her husband and marries another, she commits adultery.”
