according to the verse i supplied, what would the interpretation be for?
(either given your post ^ or not... or both)
I gave two situations above for speaking in tongues.
1Cor 14:2; and 1Cor 14:14; specifically about tongues in prayer. It's a private conversation between you and God. No need for interpretation.
However....
1Cor 14:6; But now, brethren, if
I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?
1Cor 14:7; Yet even lifeless things, either flute or harp, in producing a sound, if they do not produce a distinction in the tones, how will it be known what is played on the flute or on the harp?
1Cor 14:8; For if the bugle produces an indistinct sound, who will prepare himself for battle?
1Cor 14:9; So also you, unless you utter by the tongue speech that is clear, how will it be known what is spoken? For you will be speaking into the air.
1Cor 14:10; There are, perhaps, a great many kinds of languages in the world, and no kind is without meaning.
1Cor 14:11; If then I do not know the meaning of the language, I will be to the one who speaks a barbarian, and the one who speaks will be a barbarian
to me.
If I'm speaking out in tongues to the congregation, the words (sounds) make no sense to the congregation unless they are interpreted.
Why speak in tongues to someone if they don't understand what you are saying?
The title of this thread is interpretation of tongues. If I'm speaking to God in tongues, (as you mentioned in verse 2) no interpretation is necessary.
1Cor 14:13; Therefore let one who speaks in a tongue pray that he may interpret.
1Cor 14:16; Otherwise if you bless in the spirit only, how will the one who fills the place of the ungifted say the "Amen" at your giving of thanks, since he does not know what you are saying?
1Cor 14:17; For you are giving thanks well enough, but the other person is not edified.
There are no rules for interpretation in private prayer. However there are rules for interpretation in an assembly (service).
1Cor 14:23; Therefore if
the whole church assembles together and all speak in tongues, and ungifted men or unbelievers enter, will they not say that you are mad?
1Cor 14:26; What is the outcome then, brethren?
When you assemble, each one has a psalm, has a teaching, has a revelation,
has a tongue, has an interpretation. Let all things be done for edification.
1Cor 14:27; If anyone
speaks in a tongue, it should be by two or at the most three, and each in turn, and one must interpret;
1Cor 14:28; but if there is no interpreter, he must keep silent
in the church; and let him speak to himself and to God.
If there is no interpreter, keep your tongues and prayers to God. Then no interpretation is needed.
