New American Standard Bible (NASB)
Mark 10
2 Some Pharisees came up to Jesus, testing Him, and began to question Him whether it was lawful for a man to divorce a wife.
3 And He answered and said to them, "What did Moses command you?"
4 They said, "Moses permitted a man to write a certificate of divorce and send her away."
5 But Jesus said to them, "Because of your hardness of heart he wrote you this commandment.
6 But from the beginning of creation, God MADE THEM MALE AND FEMALE.
7 FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER,
8 AND THE TWO SHALL BECOME ONE FLESH; so they are no longer two, but one flesh.
9 What therefore God has joined together, let no man separate."
10 In the house the disciples began questioning Him about this again.
11 And He *said to them, "Whoever divorces his wife and marries another woman commits adultery against her;
12 and if she herself divorces her husband and marries another man, she is committing adultery."
