1 Corinthians 6:16; 1 Corinthians 11:27; 1 Corinthians 14:9; 1 Corinthians 14:11
What? know ye not that he which is joined to an harlot is one body? for two, saith he , shall be one flesh.
Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken ? for ye shall speak into the air.
Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me.
