Enow, you are contradicting scripture. You say the tongues were understood by the devout Jews, but tongues are not understood naturally by any man.
Acts 2:5 And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. 6 Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. 7 And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? 8 And how hear we every man in our own tongue, wherein we were born? 9 Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, 10 Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, 11 Cretes and Arabians,
we do hear them speak in our tongues the wonderful works of God. 12 And they were all amazed, and were in doubt, saying one to another, What meaneth this?
Scripture testifies that the devout Jews understood what His disciples were speaking in tongues about because it was done in their native language.
1 Corinthians 14:2 You just refuse to let scripture interpret scripture. That is a huge error in hermeneutics.
Not really. Tongue speakers always take verse 2 out of context for why Paul was saying that. From verse 1, Paul is addressing beleivers that when they desire spiritual gifts to seek the gift of prophesy out of all spiritual gifts. Paul began to show why by comparing the gift of tongues against the gift of prophesy in explaining that the gift of tongues is not a stand alone gift because the tongue speaker does not know what is being said but God does, for why prophesy is better because he who is led by the Spirit to edify, they understand what is being said.
1 Corinthians 14:1Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. 2 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. 3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
Paul repeats the exhortation again for why prophesy is the better gift to seek after than tongues.
1 Corinthians 14:12 Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
Then he addresses again the use of God's gift of tongues for why it is not a stand alone gift.
13
Wherefore let him that speaketh in an unknown tongue
pray that he may interpret.
This is about the use of tongues in the assembly that if any one speaks in tongues, they should pray that "he" that is the Lord Jesus Christ thru the Holy Spirit through another believer, will interpret that tongue being manifested in himself in the assembly.
14 For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful.
So Paul is instructing tongue speakers in the assembly to pray that someone will interpret that tongue so that the tongue speaker may understand it and that tongue is fruitful to himself as a tongue speaker for he is edified by understanding it. Paul makes that same point for others in the assembly.
15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. 16 Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? 17 For thou verily givest thanks well, but the other is not edified.
Paul was never explaining that tongues can be for private use when thru out that chapter, he is talking about why prophesy is the gift to seek after because tongues is not a stand alone gift to seek after. But the way modern tongue speakers are going, they apply that whole chapter as Paul does not know what he is talking about as tongues for private use is the better gift. You guys sure aren't exhorting the gift of prophesy as if that is the best gift to seek after. No. It's tongues for private use, because you want to believe it is God's gift of tongues when it comes with no interpretation, & it's not, because the world has that kind of babbling gibberish supernatural tongue long before Pentecost for why it can never be an alternative form of God's gift of tongues..
