Proverbs 20:25-27

Revised Standard Version

²⁵ It is a snare for a man to say rashly, “It is holy,”
    and to reflect only after making his vows.
²⁶ A wise king winnows the wicked,
    and drives the wheel over them.
²⁷ The spirit of man is the lamp of the Lord,
    searching all his innermost parts.
