'Unknown' in the Bible

A Light for revelation to the Gentiles [to disclose what was previously unknown],And [to bring] the praise and honor and glory of Your people Israel.”

For they heard them talking in [unknown] tongues (languages) and exalting and magnifying and praising God. Then Peter said,

For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you.

And when Paul laid his hands on them, the Holy Spirit came on them, and they began speaking in [unknown] tongues (languages) and prophesying.

and to another the working of miracles, and to another prophecy [foretelling the future, speaking a new message from God to the people], and to another discernment of spirits [the ability to distinguish sound, godly doctrine from the deceptive doctrine of man-made religions and cults], to another various kinds of [unknown] tongues, and to another interpretation of tongues.

So God has appointed and placed in the church [for His own use]: first apostles [chosen by Christ], second prophets [those who foretell the future, those who speak a new message from God to the people], third teachers, then those who work miracles, then those with the gifts of healings, the helpers, the administrators, and speakers in various kinds of [unknown] tongues.

For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.

He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.

Now I wish that all of you spoke in unknown tongues, but even more [I wish] that you would prophesy. The one who prophesies is greater [and more useful] than the one who speaks in tongues, unless he translates or explains [what he says], so that the church may be edified [instructed, improved, strengthened].

Now, believers, if I come to you speaking in unknown tongues, how will I benefit you unless I also speak to you [clearly] either by revelation [revealing God’s mystery], or by knowledge [teaching about God], or by prophecy [foretelling the future, speaking a new message from God to the people], or by instruction [teaching precepts that develop spiritual maturity]?

So it is with you, if you speak words [in an unknown tongue] that are not intelligible and clear, how will anyone understand what you are saying? You will be talking into the air [wasting your breath]!

There are, I suppose, a great many kinds of languages in the world [unknown to us], and none is lacking in meaning.

Wherefore let him that speaketh in an unknown tongue pray that he may interpret.

For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful.

Otherwise if you bless [and give thanks to God] in the spirit only, how will any outsider or someone who is not gifted [in spiritual matters] say the “Amen” [of agreement] to your thanksgiving, since he does not know what you are saying?

Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.

In the Law it stands written, "'By men of unknown tongues and by the lips of an unknown nation will I speak to this People, but even then they will not listen to Me', says the Lord."

Therefore, [unknown] tongues are [meant] for a [supernatural] sign, not to believers but to unbelievers [who might be receptive]; while prophecy [foretelling the future, speaking a new message from God to the people] is not for unbelievers but for believers.

So then, if the whole church gathers together and all of you speak in [unknown] tongues, and outsiders or those who are not gifted [in spiritual matters] or unbelievers come in, will they not say that you are out of your mind?

If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.

Therefore, believers, desire earnestly to prophesy [to foretell the future, to speak a new message from God to the people], and do not forbid speaking in unknown tongues.

As unknown, and yet well known; as dying, and, behold, we live; as chastened, and not killed;

And was unknown by face unto the churches of Judaea which were in Christ:

Let all bitterness and all passionate feeling, all anger and loud insulting language, be unknown among you--and also every kind of malice.

Be hospitable to one another without complaint.
