4 The sun three times as much, burneth the mountains, breathing out fiery vapours, and shining with his beams, he blindeth the eyes.

6 And the moon in all in her season, is for a declaration of times and a sign of the world.
7 From the moon is the sign of the festival day, a light that decreaseth in her perfection.
8 The month is called after her name, increasing wonderfully in her perfection
