Matthew 19:3-9

19:3 Pharisees came to him, testing him and saying, “Is it lawful for a man to divorce his wife for any reason?”

19:4 He answered, “Haven’t you read that he who made them from the beginning made them male and female,

19:5 and said, ‘For this cause a man shall leave his father and mother, and shall be joined to his wife; and the two shall become one flesh?’

19:6 So that they are no more two, but one flesh. What therefore God has joined together, don’t let man tear apart.”

19:7 They asked him, “Why then did Moses command us to give her a certificate of divorce and divorce her?”

19:8 He said to them, “Moses, because of the hardness of your hearts, allowed you to divorce your wives, but from the beginning it has not been so.

19:9 I tell you that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and he who marries her when she is divorced commits adultery.”
