Midrash su Salmi 31:21

Rabbi Yehudah Bar Simon opened with (Daniel 2:22): "He reveals the deep and secret. He knows what is in the darkness, and the light dwells with Him." "He reveals the deep"--this is Hell, as it says (Proverbs 9:18): "He does not know there are spirits there," and it says (Isaiah 30:33): "deep and large". "And secret"--this is Paradise, as it says (Isaiah 4:6): "for a cover and refuge from storm and rain," and it says (Psalms 31:21): "You hide them in the cover of Your presence." Alternatively, "he reveals the deep and secret"--these are the acts of the wicked, as it says (Isaiah 29:15): "Woe to the ones who seek deep from God to make their counsel secret." "And secret"--these are the acts of the wicked, as the verse states. "He knows what is in the dark"--these are the acts of the wicked, as it says in Isaiah: "Their acts are in the dark." "The light dwells with Him"--these are the acts of the righteous, as it is written (Proverbs 4:18): "The path of the righteous is like the light at dawn," and it says (Psalms 97:11): "Light is sown for the righteous." Rabbi Abba Srungia said: "The light dwells with Him"--this is the Messiah, as it says (Isaiah 60:1): "Arise, shine, for your light has come." Rabbi Yehudah Bar Simon said: From the beginning of the creation of the world, "he revealed the dark and secret". "In the beginning God created the heavens," but it is not explained. Where is it explained? Here (Isaiah 40:22): "He stretches out the heavens like a curtain." "And the land," but it is not explained. Where is it explained? Here (Job 37:6): "For He says to the snow: 'Fall on the earth.'" and (Job 38:38) "When the dust runs into a mass, and the clods cleave together." "And God said: 'Let there be light,'" and it is not explained. Where is it explained? (Psalms 104:2) "You cover Yourself with light like a garment."
