Speaking with tongues
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;— KJV, Mark 16:17
They shall speak with new tongues. What does this mean? What it means is that the bible is going to be translated into other languages than Hebrew, Greek and Latin.
This title then read many of the Jews: for the place where Jesus was crucified was nigh to the city: and it was written in Hebrew, and Greek, and Latin. — KJV, John 19:20
So it was in Acts 2 that the translation of the bible was made possible through the gift of tongues.
And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. — KJV, Acts 2:4
The speaking in tongues gift is necessary to make it possible for the disciples to go into all the world and preach the gospel to every creature.
 And he said unto them,Go ye into all the world, and preach the gospel to every creature.
 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.— KJV, Mark 16:15-18
Because the scripture before the gift of tongues only existed in Greek, Hebrew and Latin.
So the speaking on tongues gift made it possible for the AV1611 to be created and the Karl XII:s bibel to be created. Because now, with the gift of tongues, the bible could be translated from Hebrew, Greek and Latin to the other languages of the world.
