Neither did Paul seek a human language linguistic expert/interpreter to understand his so-called "babbling nonsense".
Neither can, to this day, one be found since "he who speaks in tongues does not speak to men(all the nations/languages in the world)
for he speaks to GOD and no one understand him." = 1 Cor 14:1
Search the world over with every linguistic expert you can find = no one will understand that which belongs to God.
Peace
FYI Brother a linguist is not an expert on the Gifts of the Holy Spirit. They are a secular humanistic approach to explaining spiritual things which they cannot understand if they are not born-again. Like listening to an atheist preach the gospel. The human intellect is unlearned because the Linguist approach is from the flesh(human reasoning) not discernment from the word of God.
