with stammering [la`eg] lips [saphah] and another ['acher] tongue [lashown] will he
speak [dabar] to this people [`am]. KJV-Interlinear
11 For by
people of strange lips and with a foreign tongue the LORD will speak to this
Tongues is the prophecy, 1 Cor. 14:21. However, tongues is not an unintelligible jabber, but identified here as foreign languages.
So since the Jews and anyone else along with them that had been ignoring God and doctrine, then God would close their eyes, which they were not using anyway, and speak to them not in their own language, because they refused to listen in their own language, and therefore speak to them in a language that they did not know, namely a foreign language.
Their eyes were important in that when Jesus came, He fulfilled numerous prophecies, performed numerous miracles, matched all of the prophetic signs, and yet they refused to see. They rejected all of the clear signs that were right in front of them. And not only in front, but had been there for several years.
Rejection and defiance were ingrained in the souls of the Jews, as well as the gentiles. No one stood up for Jesus, and thus He was tried, convicted, and executed, having committed no crime or transgression against anyone.
After, the Cross at Passover, fifty days later at the Feast of Pentecost, the Holy Spirit came upon and indwelled the apostles and they spoke publicly in tongues. These tongues were languages, languages of the region, but foreign to Judah.
To the unsuspecting, they sounded like jabber.
If you have ever been a market or foreign place where the language spoken is not known to you, and lots of people are speaking, then it is jabber to you, because you do not know or understand it.
And to the Jews, this is the greatest of humiliations.
They did not teach truth in their own language, and therefore God used foreign languages to teach truth. And so much so that each foreign person, understood the gospel, in their own language, even though the Hebrew apostles were speaking.
A miracle to be sure.
But it was also a temporary miracle, as all of the gifts back then were temporary gifts that were given in order to establish the authority of the apostles and their message, and once that authority became recognized across the region, then the gifts were ended.
So the clarity of ones own language, was turned to the jabber of a foreign language in order to teach truth.
Some recognized the miracle, while many did not.
After many centuries of non-existence, some tried to reinvent the gift back in the 1800’s, using false and phony gibberish, which really was gibberish. And some still try to impress others with invented gibberish even in our present day. But do not be fooled.
It served a legitimate purpose back in Pauls day, and then was no more. Its purpose in our day, is apostate, which further demonstrates the degree of indifference and corruption toward truth, by using invented tricks, in these final days as our own dispensation approaches its end.
The real miracle for indifference at the end of our dispensation will be the Rapture, when believers will be removed, wherein back in Pauls day, that indifference served to remove the teaching of doctrine from the Jews.
