Mark 10:1-9

From there he went to the area of Judea across the Jordan. A crowd of people, as was so often the case, went along, and he, as he so often did, taught them. Pharisees came up, intending to give him a hard time. They asked, “Is it legal for a man to divorce his wife?” Jesus said, “What did Moses command?” They answered, “Moses gave permission to fill out a certificate of dismissal and divorce her.” Jesus said, “Moses wrote this command only as a concession to your hardhearted ways. In the original creation, God made male and female to be together. Because of this, a man leaves father and mother, and in marriage he becomes one flesh with a woman—no longer two individuals, but forming a new unity. Because God created this organic union of the two sexes, no one should desecrate his art by cutting them apart.”
