Midrash su Amos 3:8

(Ib. b) The Caesar said unto R. Joshua b. Chanania: "Your God is likened unto a lion, as the passage says (Amos 3, 8) The Lion hath roared, who will not fear. What is there remarkable about it? Does not a hunter kill a lion?" "He is not likened unto an ordinary lion," was the reply of R. Joshua; "but He is likened unto the lion of the forest of Ilai." "If so then I would like to see such a lion," came the request of the Caesar. "You cannot see it," R. Joshua answered. "But I must see it," insisted the Caesar. Whereupon R. Joshua prayed and caused the lion [of the forest Ilai] to move from its place. When it reached a distance of four hundred Parsahs [from Rome] it gave forth a roar which caused miscarriage to the pregnant women and the tower of Rome to tremble to the point of falling. When it reached three hundred Parsahs, it gave forth another roar, which caused the falling out of the teeth of every person, and the Caesar himself fell off the throne. The Caesar then said to R. Joshua: "I beg of thee, pray for mercy that it should return back to its place." R. Joshua thereupon prayed and it caused the lion to return to its place.

And the smoke thereof ascended as the smoke of a furnace (Exod. 19:18). What furnace? Perhaps it is comparable to this furnace? Therefore Scripture says: And the mountain burned with fire (Deut. 4:11). Why then does Scripture say Of a furnace? It does so only in order to transmit to the ear that which it can comprehend. Similarly it says: The lion hath roared, who will not fear (Amos 3:8), yet who instilled strength and power in the lion, if not He? We describe Him by the qualities given to His creations, so that the ear may hear what it is able to comprehend. Likewise, Behold, the glory of the God of Israel came from the way of the east; and His voice was like the sound of many waters; and the earth did shine with His glory (Ezek. 43:2). Who instilled strength and force into the waters? Was it not He? Here again we describe Him merely by the qualities possessed by His creations, so that the ear may comprehend (what it hears).

“To whom the word of the Lord came… until the end of eleven years of Zedekiah son of Josiah, king of Judah, until the exile of Jerusalem in the fifth month.” (Jeremiah 1:2-3) R’ Avon said: the lion (ari) came up during the constellation of the lion and destroyed Ariel. ‘The lion came up’ refers to Nebuchadnezzar the wicked, as it is written “A lion has come up from his thicket…” (Jeremiah 4:7) ‘In the constellation of the lion’, “…until the exile of Jerusalem in the fifth month.” (Jeremiah 1:3) ‘And destroyed Ariel’, “Woe, Ariel, Ariel, the city wherein David encamped!” (Isaiah 29:1) This happened in order that the lion would come in the constellation of the lion and rebuild Ariel. ‘The lion would come’ refers to the Holy One, as it is written “A lion has roared; who will not fear?” (Amos 3:8) ‘In the constellation of the lion’, “…and I will turn their mourning into joy…” (Jeremiah 31:12) ‘And rebuild Ariel’, “The Lord is the builder of Jerusalem; He will gather the outcasts of Israel.” (Psalms 147:2)
