Midrash su Deuteronomio 28:47

(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."

Once, R. Yochanan b. Zakkai went up to Maon Yehudah, where he saw a young girl picking barley from under the dung of a horse, whereupon he asked (the bystanders): Did you see that young girl? What is she? They: A Hebrew. He: Who owns this horse? They: An Arab rider. R. Yochanan to his disciples: All of my days I was aggrieved over this verse, reading it and not knowing what it meant — "If you do not know, you fairest among the women" — If you did not wish to subserve Heaven, you will subserve gentiles. If you did not wish to pay the half-shekel for a head to Heaven, you will pay fifteen shekels in the kingdom of your foes. If you did not wish to repair the roads and the thoroughfares for the festival pilgrims, you will repair the station houses for the pilgrims to the royal vineyards. And thus is it written (Devarim 28:47-48) "Because you would not serve the L rd your G d in joy and gladness … you will serve your foes in hunger and in thirst, in nakedness and in want of all." What is "in want of all"? In want of sanity. Variantly: "in want of all" — in want of Torah study.
