4 Bible Verses about Speaking In Tongues

And it came to pass, while Apollos was in Corinth, Paul having come through the upper regions came down into Ephesus: and found certain disciples, and said to them, Have you received the Holy Ghost, having believed? And they said to him, But we have not heard if the Holy Ghost is (given). And he said, Into what then were you baptized? And they said, Into the baptism of John.read more.
And Paul said, John baptized with the baptism of repentance, saying unto the people, that they should believe on the one coming after him, that is Jesus. And they, having heard, were baptized into the name of the Lord Jesus; and Paul having laid his hands on them, the Holy Ghost came on them; and they continued to speak with tongues, and prophesy. And they were all about twelve men.

Divine love never falls: but whether there are prophecies, they shall be done away; whether there are tongues, they shall cease; whether there is knowledge, it shall vanish away.

For the one speaking with a tongue speaks not to men, but to God; for no one hears him; but he speaks mysteries in the spirit: but the one prophesying speaks to men edification, exhortation, and comfort. The one speaking with a tongue edifies himself; but the one prophesying edifies the church.read more.
But I wish you all to speak with tongues, but rather that you may prophesy: but greater is the one prophesying, than the one speaking with tongues, unless he may interpret, in order that the church may receive edification. But now, brethren, if I may come unto you speaking with tongues, what shall I profit you, unless I shall speak to you either in revelation, or knowledge, or prophecy, or in instruction? Nevertheless things without life, giving forth a voice, whether pipe or harp, if it may not give a distinction to the sounds, how shall it be known what is piped, or what is harped? For if indeed the trumpet may give an uncertain sound, who will prepare himself for the war? Thus also if you through the tongue may give an indistinct word, how will that which is spoken be known? for you will be speaking into the air. If it so happens that there are so many kinds of voices in the world, and nothing without a voice; if then I do not understand the power of the voice, I will be a barbarian to the one speaking, and the one speaking will be a barbarian to me. So also you, since you are zealots of spirits, seek that you may abound unto the edification of the church. Therefore let the one speaking with a tongue, pray that one may interpret. For if I pray with a tongue, my spirit is praying, but my mind is not fruitful. Then what is it? I will pray with my spirit, and I will pray with my mind also: I will sing with my spirit, and I will sing with my mind also. Since if you may bless with the spirit, how will one occupying the place of the unlearned say Amen to your blessing? since he does not know what you are saying. For you indeed bless beautifully, but the other is not edified. I thank God, I speak with tongue more than you all: but I would rather speak five words in the church with my understanding, so that I may indeed teach others, than ten thousand words in a tongue. Brethren, be not children in intellect: but be infants in evil, but be perfect in intellect. It has been written in the law; I will speak to this people with other tongues and with the lips of others; and thus they will not hearken unto me, says the Lord. So tongues are for a sign, not to those who believe, but to the unbelievers: and prophecy is not for the unbelievers, but for the believers. Then if the whole church may come together, and all may speak with tongues, and the unlearned or unbelievers may come in, will they not say that you are gone mad? But if all may prophesy, and some unbeliever or unlearned person may come in, he is convicted by all, he is discerned by all; the secrets of his heart are made manifest; and thus falling upon his face he will worship God, proclaiming that God is truly in you. Then what is it, brethren? When you may come together, each one has a psalm, has a lesson, has a revelation, has a tongue, has an interpretation. Let all things be done to edification. If one speaks with a tongue, let it he by twos, or at most by threes, and separately; and let one interpret; but if there may be no interpreter, let him keep silent in the church; but let him speak to himself, and to God.

So, my brethren, be zealous to prophesy, and do not forbid to speak with tongues; but let all things be done decently and in order.
