לֹֽא־יָמִ֞ישׁ עַמּ֤וּד הֶֽעָנָן֙ יוֹמָ֔ם וְעַמּ֥וּד הָאֵ֖שׁ לָ֑יְלָה לִפְנֵ֖י הָעָֽם׃ (פ)
낮에는 구름 기둥, 밤에는 불 기둥이 백성 앞에서 떠나지 아니하니라
Zohar
Rabbi Shimeon said: "pillar of cloud during the day" (Ex. 13:22): this is Avraham (chesed). "And pillar of fire during the night": this is Itzchak (gevurah). And both of them are found in the Shechinah, and what Rabbi Abba said (yesod) is certainly obvious, that on through this, at this level, they are found.
