(Devarim 33:2) "He appeared from Mount Paran": There are four "appearances." The first, in Egypt, viz. (Psalms 80:2) "Shepherd of Israel, hear, who leads Joseph as a flock; Dweller among the cherubs — appear." The second, at the giving of the Torah, viz. "He appeared from Mount Paran." The third, in the days of Gog and Magog, viz. (Psalms 94:1) "A G-d of vengeance is the L-rd — G-d of vengeance, appear!" The fourth, in the days of the Messiah, viz. (Ibid. 50:2) "From Zion, the quintessence of beauty, G-d appeared."
