KJV:
He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
NASB:
One who speaks in a tongue edifies himself; but one who prophesies edifies the church.
KJV:
I would that ye all spake with tongues, but rather that ye prophesied: for greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
NASB:
Now I wish that you all spoke in tongues, but even more that you would prophesy; and greater is one who prophesies than one who speaks in tongues, unless he interprets, so that the church may receive edifying.
KJV:
Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?
NASB:
But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?
KJV:
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.
NASB:
So also you, unless you utter by the tongue speech that is clear, how will it be known what is spoken? For you will be speaking into the air.
KJV:
Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
NASB:
Therefore let one who speaks in a tongue pray that he may interpret.
KJV:
For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful.
NASB:
For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
KJV:
I thank my God, I speak with tongues more than ye all:
NASB:
I thank God, I speak in tongues more than you all;
KJV:
Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
NASB:
however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
KJV:
Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.
NASB:
So then tongues are for a sign, not to those who believe but to unbelievers; but prophecy is for a sign, not to unbelievers but to those who believe.
