6 Bible Verses about Speaking In Tongues

And it came to pass, in Apollos' being in Corinth, Paul having gone through the upper parts, came to Ephesus, and having found certain disciples, he said unto them, 'The Holy Spirit did ye receive -- having believed?' and they said unto him, 'But we did not even hear whether there is any Holy Spirit;' and he said unto them, 'To what, then, were ye baptized?' and they said, 'To John's baptism.'read more.
And Paul said, 'John, indeed, did baptize with a baptism of reformation, saying to the people that in him who is coming after him they should believe -- that is, in the Christ -- Jesus;' and they, having heard, were baptized -- to the name of the Lord Jesus, and Paul having laid on them his hands, the Holy Spirit came upon them, they were speaking also with tongues, and prophesying, and all the men were, as it were, twelve.

and to another faith in the same Spirit, and to another gifts of healings in the same Spirit; and to another in-workings of mighty deeds; and to another prophecy; and to another discernings of spirits; and to another divers kinds of tongues; and to another interpretation of tongues:

and ye are the body of Christ, and members in particular. And some, indeed, did God set in the assembly, first apostles, secondly prophets, thirdly teachers, afterwards powers, afterwards gifts of healings, helpings, governings, divers kinds of tongues; are all apostles? are all prophets? are all teachers? are all powers?read more.
have all gifts of healings? do all speak with tongues? do all interpret? and desire earnestly the better gifts; and yet a far excelling way do I shew to you:

The love doth never fail; and whether there be prophecies, they shall become useless; whether tongues, they shall cease; whether knowledge, it shall become useless;

for he who is speaking in an unknown tongue -- to men he doth not speak, but to God, for no one doth hearken, and in spirit he doth speak secrets; and he who is prophesying to men doth speak edification, and exhortation, and comfort; he who is speaking in an unknown tongue, himself doth edify, and he who is prophesying, an assembly doth edify;read more.
and I wish you all to speak with tongues, and more that ye may prophecy, for greater is he who is prophesying than he who is speaking with tongues, except one may interpret, that the assembly may receive edification. And now, brethren, if I may come unto you speaking tongues, what shall I profit you, except I shall speak to you either in revelation, or in knowledge, or in prophesying, or in teaching? yet the things without life giving sound -- whether pipe or harp -- if a difference in the sounds they may not give, how shall be known that which is piped or that which is harped? for if also an uncertain sound a trumpet may give, who shall prepare himself for battle? so also ye, if through the tongue, speech easily understood ye may not give -- how shall that which is spoken be known? for ye shall be speaking to air. There are, it may be, so many kinds of voices in the world, and none of them is unmeaning, if, then, I do not know the power of the voice, I shall be to him who is speaking a foreigner, and he who is speaking, is to me a foreigner; so also ye, since ye are earnestly desirous of spiritual gifts, for the building up of the assembly seek that ye may abound; wherefore he who is speaking in an unknown tongue -- let him pray that he may interpret; for if I pray in an unknown tongue, my spirit doth pray, and my understanding is unfruitful. What then is it? I will pray with the spirit, and I will pray also with the understanding; I will sing psalms with the spirit, and I will sing psalms also with the understanding; since, if thou mayest bless with the spirit, he who is filling the place of the unlearned, how shall he say the Amen at thy giving of thanks, since what thou dost say he hath not known? for thou, indeed, dost give thanks well, but the other is not built up! I give thanks to my God -- more than you all with tongues speaking -- but in an assembly I wish to speak five words through my understanding, that others also I may instruct, rather than myriads of words in an unknown tongue. Brethren, become not children in the understanding, but in the evil be ye babes, and in the understanding become ye perfect; in the law it hath been written, that, 'With other tongues and with other lips I will speak to this people, and not even so will they hear Me, saith the Lord;' so that the tongues are for a sign, not to the believing, but to the unbelieving; and the prophesy is not for the unbelieving, but for the believing, If, therefore, the whole assembly may come together, to the same place, and all may speak with tongues, and there may come in unlearned or unbelievers, will they not say that ye are mad? and if all may prophecy, and any one may come in, an unbeliever or unlearned, he is convicted by all, he is discerned by all, and so the secrets of his heart become manifest, and so having fallen upon his face, he will bow before God, declaring that God really is among you. What then is it, brethren? whenever ye may come together, each of you hath a psalm, hath a teaching, hath a tongue, hath a revelation, hath an interpretation? let all things be for building up; if an unknown tongue any one do speak, by two, or at the most, by three, and in turn, and let one interpret; and if there may be no interpreter, let him be silent in an assembly, and to himself let him speak, and to God.

so that, brethren, earnestly desire to prophesy, and to speak with tongues do not forbid; let all things be done decently and in order.
