Kabbalah Keluaran 3:2: Zohar

וַ֠יֵּרָא מַלְאַ֨ךְ יְהֹוָ֥ה אֵלָ֛יו בְּלַבַּת־אֵ֖שׁ מִתּ֣וֹךְ הַסְּנֶ֑ה וַיַּ֗רְא וְהִנֵּ֤ה הַסְּנֶה֙ בֹּעֵ֣ר בָּאֵ֔שׁ וְהַסְּנֶ֖ה אֵינֶ֥נּוּ אֻכָּֽל׃

Lalu malaikat Yang Mahakekal menampakkan diri kepadanya dalam nyala api dari tengah-tengah semak duri. Ia melihat, dan tampaklah semak duri itu menyala dengan api, tetapi semak duri itu tidak dimakan api.

Zohar

R. Isaac said: ‘Why, in one place in the Psalms does it say “The angel of the Lord encampeth round about them that fear him and delivereth them” (Ps. 34, 8), in the singular, and in another place, “For he will give his angels charge over thee” (Ibid. 91, 11), in the plural? The reason is that the term “angels” is a reference to angels proper, whereas in the verse: “The angel of the Lord encampeth”, the reference is to the Shekinah, as in the verse: “And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush” (Ex. 3, 2). Thus “the angel of the Lord encampeth round about those who fear him” to deliver them; and when the Shekinah abides within a man, ever so many holy legions rally round him.

The bush was indeed in that region of holiness and clave to it, for all things cleave to one another, the pure and the impure, there is no purity except through impurity;
