Sirach 43:4-6

New Revised Standard Version Updated Edition

⁴ A man tending^[a] a furnace works in burning heat,
    but three times as hot is the sun scorching the mountains;
when it breathes out fiery vapors
    and when it shines forth its rays, it blinds the eyes.^(A)
5 Great is the Lord who made it;
    at his orders it hurries on its course.^(B)

⁶ It is the moon that marks the changing seasons,^[b]
    governing the times, an everlasting sign.^(C)
