Many Messianics believe that Hebrew will be the restored language of the Millennium. I'm not sure. I think something like it will be restored. Even if we postulate that the Adamic tongue is what will be restored its early vocabulary would be insufficient to meet the demands of the 21st century. Hebrew itself has evolved considerably over the millennia and what we call modern Hebrew does differ in a lot of areas to the classical variety of the Tanakh. Moreover, even the Hebrew of the Tanakh has evolved and has different styles. For all we know, YHWH may even restore a completely new language. I think it is important to learn Hebrew if you can, or at least get some knowledge of classical Hebrew for scripture study, but I would not advocate exclusivity. All language today is corrupt. And modern Hebrew doesn't even get Yahweh's Name right since the W sound has evolved/changed into a V and in the ancient variety some consonants also doubled up as vowels.

So just as I believe the King James Bible translators who said there was profit in using many different translations so I believe there is profit in using many languages and so avoid tunnel-vision. As far as the Bible is concerned we promote Hebrew, Aramaic and Greek versions and believe we have something to learn from all of them.
