What does Proverbs 12:7 mean?

Solomon notes again that the wicked will experience an abrupt end. Reliance on worldly resources and money is foolish (Proverbs 11:4–7). Trusting in an all-powerful and all-good God is always a safe choice (Proverbs 10:25). In fact, the evil person's attempt to destroy others is likely to lead to his own ruin (Psalm 9:15–16).

The book of Daniel relates the story of King Darius's high officials who despised Daniel and tried to destroy him. They persuaded Darius to pass a law that forbade everyone from requesting anything of any god or man for thirty days except of Darius. The penalty for breaking this law was death by hungry lions. Daniel broke the law by praying to the true God. He was subsequently thrown into a den of lions. However, the Lord protected Daniel, and Darius brought him out of the den. He then commanded that Daniel's accusers be tossed to the lions. "The lions overpowered them and broke all their bones in pieces" (Daniel 6:24). As for righteous Daniel, he prospered (Daniel 6:28).

Ultimately, the wicked will be consigned to hell (Revelation 20:11–15), but the righteous will enjoy eternal bliss in heaven (Revelation 21:1–4).
