Mark 10:3-8

10:3 He answered them, “What did Moses command you?” 10:4 They said, “Moses permitted a man to write a certificate of dismissal and to divorce her.” 10:5 But Jesus said to them, “He wrote this commandment for you because of your hard hearts. 10:6 But from the beginning of creation he made them male and female. 10:7 For this reason a man will leave his father and mother, 10:8 and the two will become one flesh. So they are no longer two, but one flesh.
