Do you have any scripture that when Paul spoke in tongues it was another language? Of all the scripture that pertains towards speaking in tongues all differ from the one single example in the Book of Acts. In fact, most other scripture describing speaking in tongues indicates "utterings and groanings." That for certain cannot be considered a form of language. But it's still considered speaking in tongues in the Bible.
Examples of no one claiming speaking in tongues was other languages someone could understand:
1. Acts 19:6 And when Paul had laid his hands on them, the Holy Spirit came on them, and they began speaking in tongues and prophesying. 7 There were about twelve men in all.
2. Mark 16:17 And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; 18 they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.”
3. 1 Corinthians 14:2 For anyone who speaks in a tongue does not speak to people but to God. Indeed, ""no one understands them;"" they utter mysteries by the Spirit.
...there's many more but "none of them" say someone can understand them because it's a human language.
So basically, "one verse" has the example of (human language) and the rest of the verses claim it's speaking to God and no one can understand it.
Since every verse "but one" shows us no human is able to understand it, wouldn't most of the Biblical examples sound gibberish then?
Yes it would.
