Matthew 19:7 WEB

⁵  and said, 'For this cause a man shall leave his father and mother, and shall join to his wife; and the two shall become one flesh?'

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

⁷  They asked him, 'Why then did Moses command us to give her a bill of divorce, and divorce her?'

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.

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.'
