Sirach 43:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ A man tending^[a] a furnace works in burning heat,
    but three times as hot is the sun scorching the mountains;
it breathes out fiery vapours,
    and its bright rays blind the eyes.
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,^[b]
    governing the times, their everlasting sign.
