Mark 10:2-9 (New International Version)

 ²Some Pharisees came and tested him by asking, "Is it lawful for a man to divorce his wife?"

 ³"What did Moses command you?" he replied.

 ⁴They said, "Moses permitted a man to write a certificate of divorce and send her away."

 ⁵"It was because your hearts were hard that Moses wrote you this law," Jesus replied. ⁶"But at the beginning of creation God 'made them male and female.'^{[a] 7}'For this reason a man will leave his father and mother and be united to his wife,^{[b] 8}and the two will become one flesh.'^[c] So they are no longer two, but one. ⁹Therefore what God has joined together, let man not separate."
