He appointed the moon for seasons:
the sun knoweth his going down.
Thou makest darkness, and it is night:
wherein all the beasts of the forest do creep forth.
The young lions roar after their prey,
and seek their meat from God.
The sun ariseth, they gather themselves together,
and lay them down in their dens.
Man goeth forth unto his work
and to his labour until the evening.
(Psalms 104: 19-23)
