Zephaniah 3:9

For then will I turn to the peoples a tongue for her generation, that all may call on the name of the Lord, to serve him under one yoke.

For then will I turn to the people a pure language, that they may all call upon the name of the Lord, to serve him with one consent.

For then I will purify the lips of the peoples, that they may all call on Yahweh’s name, to serve him shoulder to shoulder.
