KJV
And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The LORD is my God.
Hebrew (Masoretic)
וְהֵבֵאתִ֤י אֶת־ הַשְּׁלִשִׁית֙ בָּאֵ֔שׁ וּצְרַפְתִּים֙ כִּצְרֹ֣ף אֶת־ הַכֶּ֔סֶף וּבְחַנְתִּ֖ים כִּבְחֹ֣ן אֶת־ הַזָּהָ֑ב ה֣וּא׀ יִקְרָ֣א בִשְׁמִ֗י וַֽאֲנִי֙ אֶעֱנֶ֣ה אֹת֔וֹ אָמַ֙רְתִּי֙ עַמִּ֣י ה֔וּא וְה֥וּא יֹאמַ֖ר יְהוָ֥ה אֱלֹהָֽי׃ ס
Septuagint (LXX)
καὶ διάξω τὸ τρίτον διὰ πυρὸς καὶ πυρώσω αὐτούς ὡς πυροῦται τὸ ἀργύριον καὶ δοκιμῶ αὐτούς ὡς δοκιμάζεται τὸ χρυσίον αὐτὸς ἐπικαλέσεται τὸ ὄνομά μου κἀγὼ ἐπακούσομαι αὐτῷ καὶ ἐρῶ λαός μου οὗτός ἐστιν καὶ αὐτὸς ἐρεῖ κύριος ὁ θεός μου
