Quotation for Gittin 62:8

R. Huna and R. Chisda were both sitting. When G'niba was approaching them, one said: "Let us rise for a great scholar." To which the other replied: "Shall we rise for that quarulous man?" Meantime the latter reached them. "In what subject are you discussing now," G'niba inquired of them. "Concerning Ruchoth (winds)," came the response. He then said to them: "Thus said R. Shanan b. Raba, in the name of Rab: 'Four different winds are blowing daily, and the northerly wind accompanies each of them; for, if it were not for the northerly wind which accompanies all the winds, the world would not be able to exist even a short time. The southerly wind is the severest of all, and if not for the [angel on winds] Ben Netz, who stops its severity with his wings, it would destroy the entire world, as it is said (Ib. 39, 26) Is it through thy understanding that the hawk (Netz) flieth along, and spreadeath out his wings towards the south?'"

Raba and R. Nachman were both sitting when R. Nachman b. Jacob who, seated in a golden chariot covered with a green colored cloak, passed them by. Raba went to greet him, but R. Nachman did not; for he said: "R. Nachman must be one of the representatives of the Exhilarch. Raba might need him [for business purposes;] I, however, do not need him." R. Nachman b. Isaac noticed them, and he went to him. The former uncovered his arm, remarking: "The wind Shida is blowing."
