Tzav: Chapter 18
"Who lays beams of His chambers in the waters"

Rabbi Yehuda tells about the time that God created the world, dividing the waters into two and establishing the world upon the lower half, then making a firmament between the two halves. He says that legions of angels were established to sing praises, some in the daytime and some at night, and that the abysses on the Other Side were also established where the angels of destruction dwell and where the river of fire runs. The rising smoke from the altar feeds the side of holiness and the other side as well.
