I guess you think you know more then John MacArthur? 1 Corinthians 14.2 in the New American Standard Bible 2006 written by John MacArthur he clearly explains below in the Study Bible that the distinction between the singular tongue and the plural tongues is foundational to the proper interpretation of this chapter. Paul seems to use the singular to distinguish the counterfeit gift of pagan gibberish and the plural to indicate the genuine gift of a foreign language. It was perhaps in recognition of that, that the King James Version translators added consistently the word “unknown” before every singular form.
you have to be sincere when you approach scripture, you can’t come with a bias or you will concoct fanciful ways of explaining away difficult passages, it would be better to just admit you don’t understand...Paul is not speaking of a counterfeit tongue of pagan “gibberish” in 1 Cor 14:1-4
