The Messianic vision is eerily similar to the דור הפלגה who were of one language - just instead of being AGAINST Hashem it will be FOR Hashem:
כִּֽי־אָ֛ז אֶהְפֹּ֥ךְ אֶל־עַמִּ֖ים שָׂפָ֣ה בְרוּרָ֑ה לִקְרֹ֤א כֻלָּם֙ בְּשֵׁ֣ם יְהֹוָ֔ה לְעׇבְד֖וֹ שְׁכֶ֥ם אֶחָֽד׃
For then I will convert the peoples to a pure language that all of them call in the name of the Lord, to worship Him of one accord.
[Tzfania 3-9]
