내가 내려와서 그들을 애굽인의 손에서 건져내고 그들을 그 땅에서 인도하여 아름답고 광대한 땅 젖과 꿀이 흐르는 땅 곧 가나안 족속, 헷 족속, 아모리 족속, 브리스 족속, 히위 족속, 여부스 족속의 지방에 이르려 하노라
Ramban
AND I AM COME DOWN TO DELIVER THEM. That is, “for I have revealed Myself in fire on this mountain.” This has the same meaning as in the verses: And the Eternal came down upon Mount Sinai;163Further, 19:20. Because the Eternal descended upon it in fire.164Ibid., Verse 18. It may be that [the expression come down has the same meaning here] as in the verse, I will go down now, and see whether they have done altogether according to the cry of it, which is come unto Me.165Genesis 18:21. See Ramban there (Vol. I, p. 245) where he explains that the meaning is, “I will go down from the attribute of mercy to the attribute of justice.” Here the meaning would be: “and I am come down from attribute to attribute.” I have already explained its secret there.
