Midrash su Zaccaria 11:7

R. Oshiya said: "What is the meaning of the passage (Zech. 11, 7) And I had taken unto me two staves; the one I called Graciousness (No'am), and the other I called Concord (Choblim): i.e., No'am refers to the scholars of Palestine who are polite to one another while discussing halacha. Choblim, refers to the scholars of Babylon who wounded [each other's feelings] while discussing halacha." (Ib. 4, 14) Then he said to me: 'They are the two sons of Yizhari (clear oil), that stand by the Lord, etc. (Ib., ib. 3) And two olive trees are naer it.' R. Isaac said: "This refers to the scholars of Palestine, who please each other during halachik discussions like olive oil; and the two olive trees near it, refer to the Babylonian scholars who enrage one another with bitterness during halachik discussions," just as an olive tree is bitter." It is written (Ib. 5, 9) Then did I lift up my eyes and looked, and behold, there came out two women, having the wind in their wings, and they had wings like the wings of a stork; and they lifted up the Ephah between the. earth and the heaven. Then said I to the angel that spoke to me, 'Whither are these bearing away the Ephah?' And he said unto me: 'To build a home for it in the land of Shinar.' R. Jochanan said in the name of R. Simon b. Jochai: "These two women refer to cringing submissions [to power] and haughtiness [to the weak], which came to Babylon." Did then haughtiness come to Babylon? Behold the master said elsewhere: "Ten measures of haughtiness came down upon the world of which nine were taken by Elam and the one measure was given to the entire world." Yea, their intention was to go to Babylon, but they were dragged along to Elam. You can also infer this from [the expression] of the passage to build (intended) a house in the land of Shinar. The explanation is sustained. Is then haughtiness not frequent also in Babylon? Behold the master said: "The symptom for haughtiness is poverty and [nine out of ten measures of] poverty went to Babylon." The poverty mentioned here refers to the Torah, as it is written (Songs 8, 5) We have a little sister and she has yet no breasts, whereupon R. Jochanan said: "This refer to Elam, which merited to [have cholars to] learn, but not to teach others." What is the meaning of the word Babel (Babylon)? R. Jochanan said: "A mixture of Scripture, Mishnah and Talmud." (Lam 3, 6) In dark places hath He set ms to dwell. R. Jeremiah said: "This refers to Babylon" [where the scholars are not agreeable to one another].
