Reversing Babel?

Acts 2:1-8, 11b, 14a, 16-17a, 21 - When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance. Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? … We hear them telling in our own tongues the mighty works of God.” … But Peter, standing with the eleven, lifted up his voice and addressed them: “Men of Judea and all who dwell in Jerusalem, ... This is what was uttered through the prophet Joel: ‘And in the last days it shall be, God declares, that I will pour out My Spirit on all flesh … And it shall come to pass that everyone who calls upon the Name of the Lord shall be saved.’”
