מדרש על דניאל 2:1

(Exodus 19:1) "On the third month of the exodus of the children of Israel from the land of Egypt": We are hereby apprised that we number the months from the exodus from Egypt. This tells me only of months. Whence do I derive (the same for) years? From (Numbers 1:1) "in the second year of their exodus from Egypt." This tells me only of that period (i.e., the general period of the exodus.) Whence do I derive the same for succeeding periods? From (Ibid. 33:38) "in the fortieth year of the exodus of the children of Israel from the land of Egypt in the fifth month" (Av). All this, until they entered Eretz Yisrael. Whence do I derive the same for (the period) after they entered Eretz Yisrael? From (I Kings 6:1) "In the four hundred and eightieth year of the exodus of the children of Israel from the land of Egypt." All this, until the Temple was built. Once the Temple was built, they began to count from (the time of) its building, viz. (II Chronicles 8:1) "And it was, at the end of forty years of Solomon's building of the Temple of the L rd, etc." If they did not merit numbering from its building they numbered from its destruction, viz. (Ezekiel 40:1) "in the fourteenth year after the city was smitten." If they did not merit numbering for themselves, they numbered for others, viz. (Daniel 2:1) "And in the second year of the reign of Nevuchadnezzar, etc.", and (Chaggai 1:15) "In the second year of the reign of King Darius." And it is written (Song of Songs 1:8) "If you do not know, you fairest among the women, etc." and (Devarim 28:47-48) "Because you would not serve the L rd your G d … you will serve your foes, etc."

...And in Jonah it is written, "I would rather die than live." Jonah was the son of the woman of Zarfat. He had already died once, and knew that he would have rest, and Elijah did not die. And so he said, "am I not better than my ancestors?"

And, behold, there came up out of the river seven kine … and it came to pass in the morning that his spirit was troubled (Gen. 41:2–8). In this verse the word “troubled” is written vatipa’em, and in the verse relating to Nebuchadnezzar, And Nebuchadnezzar was troubled (Dan. 2:1), it is written vattitpa’em. Pharaoh recalled his dream, but did not know its explanation, and therefore was troubled only once. Nebuchadnezzar, however, forgot the dream and its explanation, and therefore was troubled twice.²The use of the hithpael form of the word “troubled” in the quotation about Nebuchadnezzar contains a doubled tav, thus indicating two troubles, while the niphal form in the verse about Pharaoh contains one tav, signifying one trouble. That is why it is written about Him: Nebuchadnezzar dreamed dreams (ibid.). R. Yannai said: He actually had two dreams; one related to an image and the other to a tree. Then the king commanded to call the magicians, and the astrologers, and the sorcerers (ibid., v. 2). Written without the tav, the magicians are those who inquire of the bones of the dead; the astrologers are those who examine the planetary constellations (for their answer). This is so because the root of the word asafim (astrologers”) means “to compel,” as it is said: Hear this, O ye that would oppress the needy (hashe’afim) (Amos 8:4); and the sorcerers are those who diminish the power of the heavenly and earthly courts.

(Gen. 41:8:) < AND IT CAME TO PASS IN THE MORNING > THAT HIS SPIRIT WAS TROUBLED (rt.: P'M), in that it was beating against him like a gong (rt.: P'M). Another interpretation (of Gen. 41:8): THAT HIS SPIRIT WAS TROUBLED. It is written of Nebuchadnezzar (in Dan. 2:1): HIS SPIRIT WAS DEEPLY TROUBLED; and it is written of Pharaoh (in Gen. 41:8): THAT HIS SPIRIT WAS TROUBLED.¹³Tanh., Gen. 10:2; Gen. R. 89:5. Why? Pharaoh knew the dream but did not know its interpretation; therefore, he was confused by one confusion. But Nebuchadnezzar knew neither the dream nor its interpretation; therefore, < he was confused > by two confusions. Thus it is stated (in Dan. 2:1): NEBUCHADNEZZAR DREAMED DREAMS. R. Hiyya said: He dreamed one dream. Then why does it say: DREAMS (in the plural)? Because he had forgotten the dream. R. Jannay says: He dreamed two dreams, one of an image (in Dan. 2:31-35) and one of a tree (in Dan. 4:7-14).

(Dan. 2:1:) NEBUCHADNEZZAR DREAMED DREAMS. ALSO HIS SPIRIT WAS DEEPLY TROUBLED, and his sleep was confused. Why? Because the dream was of himself in that it showed him his kingdom. For that reason (ibid.): AND HE SUFFERED SLEEPLESSNESS.

And to teach that we count (the years) from the exodus from Egypt, it being written "in the second year after their going out from the land of Egypt." When they came to the land, they began to count (shemitah, etc.) from their coming, as it is written (Vayikra 25:2) "When you come to the land, etc." When the Temple was built, they began to count from its building, viz. (I Kings 9:10) "And it was at the end of twenty years from Solomon's building, etc." When the Temple was destroyed, they began to count from its destruction, viz. (Ezekiel 40:1) "… in the fourteenth year of the city's being smitten." When the captivity intensified, they began to count from the captivity, viz. (Daniel 2:1) "And in the second year of the reign of Nevuchadnezzar, etc.", and (Chaggai 1:1) "And in the second year of King Darius, etc." And just as they counted for years, so they counted for months (e.g., [Shemot 19:1]) "In the third month of the exodus of the children of Israel from the land of Egypt."
