Midrash su Giobbe 37:21

R. Sala said again, in the name of R. Hamnuna: "The man who is insolent will finally stumble into idolatry; as it is said (Ib.) Yet thou hadst a harlot's forehead." And R. Nachman b. Isaac said: "An insolent man must be considered as having already stumbled into idolatry; for the passage says, thou hadst, and not thou wilt have." Rabba b. Huna said: "An insolent man may be classed with the wicked; as it is said (Pr. 21, 29) A wicked man showeth impudence in his face." And R. Nachman b. Isaac said: "It is even permitted to hate him; as it is said (Ecc. 8, 1) Aiid the boldness of his face Yeshuna (is changed). Do not read Yeshuna, but Yisanei (may be hated)." R. Joseph said: "We infer it from here [that rain is withheld on account of neglect to study the Torah] (Job 37, 21) Yet men see not the light which is bright in the skies. But the wind passeth along, and cleanseth them; i.e., light refers to the Torah; as it is said (Prov. 6, 23) For the commandment is a lamp, and the Torah is light; Which is bright in the skies, was explained in the college of R. Ishmael: 'Even when the sky is full of clouds and dew, the wind will clear them away.' "
