Mark 10:8

King James Version - American Edition

and they twain shall be one flesh: so then they are no more twain, but one flesh.

See the chapter Copy

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

What therefore God hath joined together, let not man put asunder.

What! know ye not that he which is joined to a harlot is one body? for two, saith he, shall be one flesh.

So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
