Sirach 43:8 CPDV

⁶  And the moon, in all its phases, serves to mark the seasons and to be a sign of the times.

⁷  From the moon is the sign of a feast day; it is a light which diminishes at its consummation.

⁸  A month is named according to its phases, increasing wonderfully at its culmination.

⁹  It is an instrument of the armies on high, shining gloriously in the firmament of heaven.

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