וַיְדַבֵּ֧ר יְהוָ֛ה אֲלֵיכֶ֖ם מִתּ֣וֹךְ הָאֵ֑שׁ ק֤וֹל דְּבָרִים֙ אַתֶּ֣ם שֹׁמְעִ֔ים וּתְמוּנָ֛ה אֵינְכֶ֥ם רֹאִ֖ים זוּלָתִ֥י קֽוֹל׃
Targum Jonathan on Deuteronomy
And the Lord spake with you on the mountain from the midst of the fire: you heard the voice of the Word {Dibbura}, but you saw no likeness, but only a voice speaking.
