Jesus teaching on divorce

Mark 10:2-12
[2]Some Pharisees came to him and tried to trap him. “Tell us,” they asked, “does our Law allow a man to divorce his wife?”
[3]Jesus answered with a question, “What law did Moses give you?”
[4]Their answer was, “Moses gave permission for a man to write a divorce notice and send his wife away.”
[5]Jesus said to them, “Moses wrote this law for you because you are so hard to teach.
[6]But in the beginning, at the time of creation, ‘God made them male and female,’ as the scripture says.
[7]‘And for this reason a man will leave his father and mother and unite with his wife,
[8]and the two will become one.’ So they are no longer two, but one.
[9]No human being then must separate what God has joined together.”
[10]When they went back into the house, the disciples asked Jesus about this matter.
[11]He said to them, “A man who divorces his wife and marries another woman commits adultery against his wife.
[12]In the same way, a woman who divorces her husband and marries another man commits adultery.”
