Tongues

Boyd’s Bible Dictionary:

“And the whole earth was of one language, and of one speech”
(Gen. 11:11And the whole earth was of one language, and of one speech. (Genesis 11:1)). Confusion of tongues and dispersion of peoples coincident (Gen. 11:7-97Go to, let us go down, and there confound their language, that they may not understand one another's speech. 8So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city. 9Therefore is the name of it called Babel; because the Lord did there confound the language of all the earth: and from thence did the Lord scatter them abroad upon the face of all the earth. (Genesis 11:7‑9)). “New tongues” (Mark 16:1717And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; (Mark 16:17)), is the first notice of a gift specially characteristic of the first outpouring of the Spirit. Ten days afterward the promise was fulfilled in the Pentecostal phenomenon (Acts 2:1-131And when the day of Pentecost was fully come, they were all with one accord in one place. 2And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. 3And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. 4And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. 5And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. 6Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. 7And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galileans? 8And how hear we every man in our own tongue, wherein we were born? 9Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judea, and Cappadocia, in Pontus, and Asia, 10Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, 11Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God. 12And they were all amazed, and were in doubt, saying one to another, What meaneth this? 13Others mocking said, These men are full of new wine. (Acts 2:1‑13)).
