Sirach 43:8 In-Context

6 He made the moon also to serve in her season for a declaration of times, and a sign of the world.
7 From the moon is the sign of feasts, a light that decreaseth in her perfection.
8 The month is called after her name, increasing wonderfully in her changing, being an instrument of the armies above, shining in the firmament of heaven;
9 The beauty of heaven, the glory of the stars, an ornament giving light in the highest places of the Lord.
10 At the commandment of the Holy One they will stand in their order, and never faint in their watches.
