Mark 10:5-12
10:5 But Jesus said to them, “He wrote this commandment for you because of your hard hearts.
10:6 But from the beginning of creation
he made them male and female.
10:7 For this reason a man will leave his father and mother,
10:8 and the two will become one flesh.
So they are no longer two, but one flesh.
10:9 Therefore what God has joined together, let no one separate.”
10:10 In the house once again, the disciples asked him about this.
10:11 So he told them, “Whoever divorces his wife and marries another commits adultery against her.
10:12 And if she divorces her husband and marries another, she commits adultery.”
