וַיְדַבֵּ֧ר יְהוָ֛ה אֲלֵיכֶ֖ם מִתּ֣וֹךְ הָאֵ֑שׁ ק֤וֹל דְּבָרִים֙ אַתֶּ֣ם שֹׁמְעִ֔ים וּתְמוּנָ֛ה אֵינְכֶ֥ם רֹאִ֖ים זוּלָתִ֥י קֽוֹל׃
И сказал вам Господь из среды огня; вы слышали голос слов, но не видели формы; только голос.
On the Migration of Abraham
[48] In one place the writer distinguishes things heard from things seen and hearing from sight, saying, “Ye heard a voice of words, and saw no similitude but only a voice” (Deut. 4:12), making a very subtle distinction, for the voice dividing itself into noun and verb and the parts of speech in general he naturally spoke of as “audible,” for it comes to the test of hearing: but the voice or sound that was not that of verbs and nouns but of God, seen by the eye of the soul, he rightly represents as “visible.”
