Matthew 19:4-6 HCSB
“Haven’t you read,” He replied, “that He who created them in the beginning made them male and female,” and He also said:
“For this reason a man will leave
his father and mother
and be joined to his wife,
and the two will become one flesh?
So they are no longer two, but one flesh. Therefore, what God has joined together, man must not separate.”
