What does Proverbs 15:6 mean?

There are cases in which good people suffer adversity or poverty (Psalm 22:1; Habakkuk 1:2–4). In general, however, those who live and act according to God's wisdom see the natural benefits of those choices. They certainly avoid the disastrous consequences of evil (Proverbs 10:8–11). The righteous who acquire wealth honestly hold it in trust for the Lord. They deem themselves stewards of what the Lord has given them. As a result, the Lord blesses the house of the righteous with treasure.

Abraham serves as a good example of such prosperity. Genesis 13:2 reports that "Abram was very rich in livestock, in silver, and in gold." Genesis 14:20 tells us that Melchizedek, the priest of the Most High God, blessed Abram after Abram's successful recovery of the hostages that were taken from Sodom. Abram reciprocated by giving Melchizedek a tenth of everything (Genesis 14:20). When the king of Sodom offered Abram the goods that were seized in the rescue of the hostages, Abram refused. He said, "I have lifted my hand to the LORD, God Most High, Possessor of heaven and earth, that I would not take a thread or a sandal strap or anything that is yours, lest you should say, '[An evil king has] made Abram rich'" (Genesis 14:22–23).

By contrast, money obtained by wicked efforts results in trouble (Proverbs 15:27). The book of Proverbs establishes that rejection of God, and His truth, is the primary mark of "foolishness" (Proverbs 1:7; 12:1–3).
