Sirach 43:5-7

New Revised Standard Version, Anglicised Catholic Edition

⁵ Great is the Lord who made it;
    at his orders it hurries on its course.

⁶ It is the moon that marks the changing seasons,^[a]
    governing the times, their everlasting sign.
⁷ From the moon comes the sign for festal days,
    a light that wanes when it completes its course.
