Mark 10: 2 - 16
2 And Pharisees came up and in order to test him asked, "Is it lawful for a man to divorce his wife?"
3 He answered them, "What did Moses command you?"
4 They said, "Moses allowed a man to write a certificate of divorce, and to put her away."
5 But Jesus said to them, "For 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 and be joined to his wife,
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 not man put asunder."
10 And in the house the disciples asked him again about this matter.
11 And he said to them, "Whoever divorces his wife and marries another, commits adultery against her;
12 and if she divorces her husband and marries another, she commits adultery."
13 And they were bringing children to him, that he might touch them; and the disciples rebuked them.
14 But when Jesus saw it he was indignant, and said to them, "Let the children come to me, do not hinder them; for to such belongs the kingdom of God.
15 Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it."
16 And he took them in his arms and blessed them, laying his hands upon them.
