Proverbs 20:23-25

²³A double weight is an abomination to the Lord; and a deceitful balance is not good in his sight.

²⁴A man's goings are directed of the Lord: how then can a mortal understand his ways?

²⁵It is a snare to a man hastily to consecrate some of his own property: for in that case repentance comes after vowing.
