Sirach 43:7-9

Revised Standard Version Catholic Edition

⁷ From the moon comes the sign for feast days,
    a light that wanes when it has reached the full.
⁸ The month is named for the moon,
    increasing marvelously in its phases,
an instrument of the hosts on high
    shining forth in the firmament of heaven.

⁹ The glory of the stars is the beauty of heaven,
    a gleaming array in the heights of the Lord.
