וְנִשְׁמַרְתֶּ֥ם מְאֹ֖ד לְנַפְשֹׁתֵיכֶ֑ם כִּ֣י לֹ֤א רְאִיתֶם֙ כָּל־תְּמוּנָ֔ה בְּי֗וֹם דִּבֶּ֨ר יְהוָ֧ה אֲלֵיכֶ֛ם בְּחֹרֵ֖ב מִתּ֥וֹךְ הָאֵֽשׁ׃
Take ye therefore good heed unto yourselves—for ye saw no manner of form on the day that the LORD spoke unto you in Horeb out of the midst of the fire—
Targum Jonathan on Deuteronomy
Keep then your souls diligently; for you saw no likeness on the day when the Lord spake with you in Horeb from the midst of the fire.
