1 Corinthians 14:4–19

4He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church. 5Now I would have you all speak with tongues, but rather that ye should prophesy: and greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying. 6But now, brethren, if I come unto you speaking with tongues, what shall I profit you, unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching? 7Even things without life, giving a voice, whether pipe or harp, if they give not a distinction in the sounds, how shall it be known what is piped or harped? 8For if the trumpet give an uncertain voice, who shall prepare himself for war? 9So also ye, unless ye utter by the tongue speech easy to be understood, how shall it be known what is spoken? for ye will be speaking into the air. 10There are, it may be, so many kinds of voices in the world, and no kind is without signification. 11If then I know not the meaning of the voice, I shall be to him that speaketh a barbarian, and he that speaketh will be a barbarian unto me. 12So also ye, since ye are zealous of spiritual gifts, seek that ye may abound unto the edifying of the church. 13Wherefore let him that speaketh in a tongue pray that he may interpret. 14For if I pray in a tongue, my spirit prayeth, but my understanding is unfruitful. 15What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. 16Else if thou bless with the spirit, how shall he that filleth the place of the unlearned say the Amen at thy giving of thanks, seeing he knoweth not what thou sayest? 17For thou verily givest thanks well, but the other is not edified. 18I thank God, I speak with tongues more than you all: 19howbeit in the church I had rather speak five words with my understanding, that I might instruct others also, than ten thousand words in a tongue.
