Sirach 43:9LXX

7From the moon is the sign of the festival day, a light that decreaseth in her perfection.

8The month is called after her name, increasing wonderfully in her perfection.

9Being an instrument of the armies on high, shining gloriously in the Armament of heaven.

10The glory of the stars is the beauty of heaven; the Lord enlighteneth the world on high.

11By the words of the holy one they shall stand in judgment, and shall never fail in their watches.
