The getting of treasures by a lying tongue is a vanity tossed to and fro of that seek death.
– Proverbs 21:6
The wording of this proverb is difficult and interpretations vary. The first phrase clearly speaks of acquiring wealth through deceit. Such wealth is the ill-gotten gains we frequently speak of from Proverbs (Proverbs 10:2; 13:11; 20:14). The second phrase gives two consequences of profit by deception. Some like fleeting vapor for vanity tossed to and fro. Wealth acquired through ill means does not last, or does not bring the satisfaction sought. The second consequence of ill-gotten gains is to be ensnared by death. This looks more to the judgment to come on the one who lies, cheats, and steals his way to riches.
