Zephaniah 3:9
Rahlfs Septuagint (1935) · Berean Standard Bible
ὅτι τότε μεταστρέψω ἐπὶ λαοὺς γλῶσσαν εἰς γενεὰν αὐτῆς τοῦ ἐπικαλεῖσθαι πάντας τὸ ὄνομα κυρίου τοῦ δουλεύειν αὐτῷ ὑπὸ ζυγὸν ἕνα
For then I will restore pure lips to the peoples, that all may call upon the name of the LORD and serve Him shoulder to shoulder.
