Matthew 19:4-6 Holman Christian Standard Bible (HCSB)
4 “Haven’t you read,” He replied, “that He who created them in the beginning made them male and female,” 5 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?
6 So they are no longer two, but one flesh. Therefore, what God has joined together, man must not separate.”
