What are the taechings of Jesus about christian marriage?

Mark 10:6-10

"But at the beginning of creation God 'made them male and female.' 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.' So they are no longer two, but one flesh. Therefore what God has joined together let no one separate."

10When they were in the house again, the disciples asked Jesus about this. He answered, "Anyone who divorces his wife and marries another woman commits adultery against her. And if she divorces her husband and marries another man, she commits adultry."
