2 For he that speaketh in a tongue, speaketh not unto men, but unto God: for no man heareth. Yet by the Spirit he speaketh mysteries.
5 And I would have you all to speak with tongues, but rather to prophesy. For greater is he that prophesieth, than he that speaketh with tongues: unless perhaps he interpret, that the church may receive edification.
6 But now, brethren, if I come to you speaking with tongues, what shall I profit you, unless I speak to you either in revelation, or in knowledge, or in prophecy, or in doctrine?
7 Even things without life that give sound, whether pipe or harp, except they give a distinction of sounds, how shall it be known what is piped or harped?
9 So likewise you, except you utter by the tongue plain speech, how shall it be known what is said? For you shall be speaking into the air.
11 If then I know not the power of the voice, I shall be to him to whom I speak a barbarian; and he that speaketh, a barbarian to me.
12 So you also, forasmuch as you are zealous of spirits, seek to abound unto the edifying of the church.
15 What is it then? I will pray with the spirit, I will pray also with the understanding; I will sing with the spirit, I will sing also with the understanding.
16 Else if thou shalt bless with the spirit, how shall he that holdeth the place of the unlearned say, Amen, to thy blessing? because he knoweth not what thou sayest.
19 But in the church I had rather speak five words with my understanding, that I may instruct others also; than ten thousand words in a tongue.
21 In the law it is written: In other tongues and other lips I will speak to this people; and neither so will they hear me, saith the Lord.
22 Wherefore tongues are for a sign, not to believers, but to unbelievers; but prophecies not to unbelievers, but to believers.
23 If therefore the whole church come together into one place, and all speak with tongues, and there come in unlearned persons or infidels, will they not say that you are mad?
24 But if all prophesy, and there come in one that believeth not, or an unlearned person, he is convinced of all, he is judged of all.
25 The secrets of his heart are made manifest; and so, falling down on his face, he will adore God, affirming that God is among you indeed.
26 How is it then, brethren? When you come together, every one of you hath a psalm, hath a doctrine, hath a revelation, hath a tongue, hath an interpretation: let all things be done to edification.
27 If any speak with a tongue, let it be by two, or at the most by three, and in course, and let one interpret.
28 But if there be no interpreter, let him hold his peace in the church, and speak to himself and to God.
33 For God is not the God of dissension, but of peace: as also I teach in all the churches of the saints.
34 Let women keep silence in the churches: for it is not permitted them to speak, but to be subject, as also the law saith.
35 But if they would learn any thing, let them ask their husbands at home. For it is a shame for a woman to speak in the church.
