Saying 29

Do not fret because of evildoers
    or be envious of the wicked,
for the evildoer has no future hope,
    and the lamp of the wicked will be snuffed out.

Proverbs 24:19-20

Here we go again with the same instruction that must be more needful that we would realize (see v. 1 and Psalm 37:1 and Proverbs 23:17). Psalm 73:3 shows us the tendency toward doing this: “I was envious at the arrogant, When I saw the prosperity of the wicked.”

Really there is nothing about the prosperous wicked to envy when we consider their end (no reward and his lamp put out).

Both Bildad:

The lamp of a wicked man is snuffed out;
    the flame of his fire stops burning.
The light in his tent becomes dark;
    the lamp beside him goes out. (Job 18:5-6)

and Job:

Yet how often is the lamp of the wicked snuffed out?
    How often does calamity come upon them,
    the fate God allots in his anger? (Job 21:17)

realized that God would deal with the wicked. Other passages on the light of the wicked going out: Proverbs 13:9; 20:20. The Psalmist in 73:3-16 quit envying the wicked when he went into the sanctuary and considered their “latter end” (v. 17).
