Mark 10:1-10 New Revised Standard Version (NRSV)
Teaching about Divorce
10 He left that place and went to the region of Judea and[a] beyond the Jordan. And crowds again gathered around him; and, as was his custom, he again taught them.
2 Some Pharisees came, and to test him they 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 dismissal and to divorce her.” 5 But Jesus said to them, “Because of your hardness of heart he wrote this commandment for you. 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,[b] 8 and the two shall become one flesh.’ So they are no longer two, but one flesh. 9 Therefore what God has joined together, let no one separate.”
10 Then in the house the disciples asked him again about this matter.
