Comentário sobre Salmos 19:7

and its circuit is to their ends The circuit of its orbit is from one end to the other.

His going forth is from the end of the heaven – i.e. from the east:

and none is hidden from its heat Had the sun been placed in the lowest sky, no man would be able to hide from its heat (Mid. Ps. 18:13) for the sun and the moon are in the second sky, as is stated (in Hagigah 12b): There are seven skies—Vilon, Rakia, Shehakim, Zevul, Machon, Ma’on, Aravothand he counts them in order: Vilon does not serve for anything; in Rakia are the sun, the moon, the stars, and the planets, etc.
