Proverbs 20:23-25

Revised Standard Version

²³ Diverse weights are an abomination to the Lord,
    and false scales are not good.
²⁴ A man’s steps are ordered by the Lord;
    how then can man understand his way?
²⁵ It is a snare for a man to say rashly, “It is holy,”
    and to reflect only after making his vows.
