Sirach 43:9-11

New Revised Standard Version Catholic Edition

⁹ The glory of the stars is the beauty of heaven,
    a glittering array in the heights of the Lord.
¹⁰ On the orders of the Holy One they stand in their appointed places;
    they never relax in their watches.
¹¹ Look at the rainbow, and praise him who made it;
    it is exceedingly beautiful in its brightness.
