Kabbalah zu Ijow 38:15

When the Holy One, Blessed be He, looked over the generations of wicked men, he stored the light for the righteous ones. Thus it is written, "And from the wicked their light is withholden," (Job 38:15) and, "light is sown for the righteous and gladness for those upright in hearts" (Ps. 97:11) And so, God said "Let there be light" just as it is written, "Who raised up the righteous man from the east," (Is. 41:1)

He opened the discussion by saying, "And from the wicked their light is withheld, and the high arm shall be broken" (Iyov 38:16). This passage has already been explained. Nevertheless, "And from the wicked their light is withheld" applies to Nimrod and the people of his generation, whom Abraham left, since he was "their light"; "the high arm shall be broken" alludes to Nimrod.
