Proverbs 25:3-5

Revised Standard Version Catholic Edition

³ As the heavens for height, and the earth for depth,
    so the mind of kings is unsearchable.
⁴ Take away the dross from the silver,
    and the smith has material for a vessel;
⁵ take away the wicked from the presence of the king,
    and his throne will be established in righteousness.
