What the Bible says about Miracle of Language
(From Forerunner Commentary)

Acts 2:5-11 Beginning with the Feast of Pentecost in AD 31, God opened salvation to those of any human language He chose to call. The miracle of languages seen in the apostles demonstrates that God can overcome any language barrier to enable His chosen people to call on His name in any language of men, as long as there is a new heart—a new spirit. What His people need are spiritual lips, speaking from a new heart, not carnal lips speaking Hebrew. David C. Grabbe What Is the Prophesied 'Pure Language'?
