Mark 10:5

1He arose from there and came into the borders of Judea and beyond the Jordan. Multitudes came together to him again. As he usually did, he was again teaching them.

2Pharisees came to him testing him, and asked him, “Is it lawful for a man to divorce his wife?”

3He answered, “What did Moses command you?”

4They said, “Moses allowed a certificate of divorce to be written, and to divorce her.”

5But Jesus said to them, “For your hardness of heart, he wrote you this commandment.

6But from the beginning of the creation, God made them male and female.

7For this cause a man will leave his father and mother, and will join to his wife,

8and the two will become one flesh, so that they are no longer two, but one flesh.

9What therefore God has joined together, let no man separate.”
