For he that speaketh in an unknown tongue speaketh not unto men, but unto God.
He that speaketh in an unknown tongue edifieth himself.
Now, brethren, if I come unto you speaking with tongues, what shall I profit you?
Wherefore, let him that speaketh in an unknown tongue pray that he may interpret.
For if I pray in an unknown tongue, my spirit prayeth.
Wherefore, tongues are for a sign.
Wherefore, brethren, forbid not to speak with tongues.
Though I have all faith, so that I could remove mountains, and have not tongues, I am nothing.
