What took place on the day of Pentecost ? Peter said when they spoke in tongues Acts.2:16: But this is that which was spoken by the prophet Joel.17: And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams.
On the day of Pentecost they were prophesying in tongues and it was being interpreted in 17 different tongues from the mouths of the speakers to the ears of the hearers
(Ways tongues is interpreted,)1 Cor.14: 6. Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?
(On the day of Pentecost it was interpreted because all the hearers understood in their own language. So there was the gift of tongues and the interpretation of tongues and prophecy. Three gifts on the day of Pentecost.) Acts2: And how hear we every man in our own tongue, wherein we were born?
