What are treasures of wickedness according to the Bible?

Treasures of wickedness encompass anything that is acquired or held through sinful means, providing a false sense of security without offering true spiritual profit. As depicted in Proverbs 10:2, such treasures—be they wealth, power, or self-righteousness—will not stand in the day of wrath. They may offer temporary enjoyment or influence, but they fail to deliver from death and can lead to eternal separation from God. True confidence must be found not in these worldly treasures, but in Christ's righteousness.
