Follow after love, and be emulous a of spiritual [manifestations], but rather that ye may prophesy.
For he that speaks with a tongue does not speak to men but to God: for no one hears; but in spirit he speaks mysteries.
But he that prophesies speaks to men [in] edification, and encouragement, and consolation.
He that speaks with a tongue edifies himself; but he that prophesies edifies [the] assembly.
Now I desire that ye should all speak with tongues, but rather that ye should prophesy. But greater is he that prophesies than he that speaks with tongues, unless he interpret, that the assembly may receive edification.
And now, brethren, if I come to you speaking with tongues, what shall I profit you, unless I shall speak to you either in revelation, or in knowledge, or in prophecy, or in teaching?
Even lifeless things giving a sound, whether pipe or harp, if they give not distinction to the sounds, how shall it be known what is piped or harped?
For also, if the trumpet give an uncertain sound, who shall prepare himself for war?
Thus also *ye* with the tongue, unless ye b give a distinct speech, how shall it be known what is spoken? for ye will be speaking to the air.
There are, it may be, so many kinds of voices in the world, and none of undistinguishable sound.
If therefore I do not know the power of the sound, I shall be to him that speaks a barbarian, and he that speaks a barbarian for me.
Thus *ye* also, since ye are desirous of spirits, c seek that ye may abound for the edification of the assembly.
Wherefore let him that speaks with a tongue pray that he may interpret.
For if I pray with a tongue, my spirit prays, but my understanding is unfruitful.
What is it then? I will pray with the spirit, but I will pray also with the understanding; I will sing with the spirit, but I will sing also with the understanding.
Since otherwise, if thou blessest with [the] spirit, how shall he who fills the place of the simple [Christian] say Amen, at thy giving of thanks, since he does not know what thou sayest?
For *thou* indeed givest thanks well, but the other is not edified.
I thank God I speak in a tongue more than all of you:
but in [the] assembly I desire to speak five words with my understanding, that I may instruct others also, [rather] than ten thousand words in a tongue.
Brethren, be not children d in [your] minds, but in malice be babes; but in [your] minds be grown e [men].
It is written in the law, f By people of other tongues, and by strange lips, will I speak to this people; and neither thus will they hear me, saith the Lord.
So that tongues are for a sign, not to those who believe, but to unbelievers; but prophecy, not to unbelievers, but to those who believe.
If therefore the whole assembly come together in one place, and all speak with tongues, and simple [persons] enter in, or unbelievers, will not they say ye are mad?
But if all prophesy, and some unbeliever or simple [person] come in, he is convicted of all, he is judged of all;
the secrets of his heart are manifested; and thus, falling upon [his] face, he will do homage to God, reporting that God is indeed amongst you.
