Midrash su Salmi 92:11

And he made the horns thereof upon the four corners of it (Exod. 38:2), in order to obtain forgiveness for the nation that exalted Him through four horns. The horn that came from Sinai, as it is said: And He hath lifted up a horn for His people (Ps. 148:14); the horn of the Torah: Horns hath He set at His side; and there is the hiding of His power (Hab. 3:4); the horn of the priesthood, as it is said: And My horn hast thou exalted (Ps. 92:11); and the horn of kingship, as is said: Moses knew not that the skin of his face sent forth beams (horns) (Exod. 34:29). And it is written elsewhere: And there was a king in Jeshurun (Deut. 33:5).

R. Ktina said: Six thousand years shall the world last, and one thousand it will be waste, as it is said (Isa. 2, 11) And exalted shall be the Lord alone, on that day." Abaye said: "Two thousand it will be waste, as it is said (Hos. 6, 2) He will revive us after two days." We are taught in a Baraitha in accordance with R. Ktina: "Just as the Sabbatical year causes rest [of all field work] once every seven years, so shall the world rest (be waste) one millenium in every seven millenia, as it is said (Is. 2,11) And exalted shall be the Lord alone, on that day, and there is also a verse (Ps. 92, 11) A Psalm or song for the Sabbath Day, i.e., the day which will be all Sabbath, and there is another passage (Ib. 90, 4) For a thousand years are in Thy eyes but as yesterday when it is passed. At the college of Elijah it was taught: "The world will last six thousand years, two thousand of which were a chaos (Tohu), two thousand were of Torah, and the remaining two thousand are the days of the Messiah, (Ib. b) and beause of the increase of our sins, many years of these have already elapsed, and still he has not come." Elijah said to R. Juda, the brother of R. Sala the Pious: "The world will continue for no less than eighty-five jubilaic periods, and in the last jubilaic period ben David will come." The latter asked: "Will he come at its beginning or at its end?" He answered: "I do not know." "Has this passed already, or will it come?" He also answered, "I do not know." R. Ashi, however, said: "Elijah told him thus: 'Until that time [will pass] do not wait for him. But after that time, you may wait'." R. Chana b. Tahlipha sent a message to R. Joseph: "I met a man who possessed scrolls written in Assyrian characters and in the holy language. And to my question from where he obtained it, he answered: 'I sold myself to the Roman army, and among the Persian treasures, I found it.' And it is written therein that four thousand two hundred and ninety-one years after the creation, the world will remain [like] an orphan, many years in which there will be war of whales, and many other years in which there will be the war of Gog and Magog, and the remainder will be the days of the Messiah. But the Holy One, praised be He! will not renew the world before seven thousand years will have elapsed." And R. Acha, the son of Raba said: "It was stated after five thousand years."

"But my horn hast thou exalted like that of the reêm" (Ps. 92:10). Just as the horns of the reêm are taller than those of all beasts and animals, and it gores to its right and to its left, likewise (is it with) Menachem, son of 'Ammiel, son of Joseph, his horns are taller than those of all kings, and he will gore in the future towards the four corners of the heavens, and concerning him Moses said this verse, "His firstling bullock, majesty is his, and his horns are the horns of the reêm: with them he shall gore the peoples all of them, even the ends of the earth" (Deut. 33:17). All the kings will rise up against him to slay him, as it is said, "The kings of the earth set themselves, and the rulers (take counsel together)" (Ps. 2:2). And Israel who (will be) in the Land (of Palestine) (will experience) great trouble, but in their troubles they (will be) like a green olive, as it is said, "I am anointed with fresh oil" (Ps. 92:10).
