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.
that thou mightest know the certainty of those things, wherein thou hast been instructed.
I thank my God, I speak with tongues more than ye all:
Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men.
He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
