Mark 10:2-9

2And Pharisees coming to [him] asked him, Is it lawful for a man to put away [his] wife? (tempting him).

3But he answering said to them, What did Moses command you?

4And they said, Moses allowed to write a bill of divorce, and to put away.

5And Jesus answering said to them, In view of your hard-heartedness he wrote this commandment for you;

6but from [the] beginning of [the] creation 1God made them male and female.

7For this cause a man shall leave his father and mother and shall be united to his wife,

8and the two shall be one flesh: so that they are no longer two but one flesh.

9What therefore 2God has joined together, let not man separate.
