The house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau stubble; they shall burn them and consume them, and there shall be no survivor to the house of Esau; for the Lord has spoken.
καὶ ἔσται ὁ οἶκος Ιακωβ πῦρ, ὁ δὲ οἶκος Ιωσηφ φλόξ, ὁ δὲ οἶκος Ησαυ εἰς καλάμην, καὶ ἐκκαυθήσονται εἰς αὐτοὺς καὶ καταφάγονται αὐτούς, καὶ οὐκ ἔσται πυροφόρος ἐν τῷ οἴκῳ Ησαυ, διότι κύριος ἐλάλησεν.
וְהָיָה֩ בֵית־יַעֲקֹ֨ב אֵ֜שׁ וּבֵ֧ית יֹוסֵ֣ף לֶהָבָ֗ה וּבֵ֤ית עֵשָׂו֙ לְקַ֔שׁ וְדָלְק֥וּ בָהֶ֖ם וַאֲכָל֑וּם וְלֹֽא־יִֽהְיֶ֤ה שָׂרִיד֙ לְבֵ֣ית עֵשָׂ֔ו כִּ֥י יְהוָ֖ה דִּבֵּֽר׃
