What does Proverbs 10:6 mean?

This is a common theme in the book of Proverbs. Those who live according to godliness are more likely to experience success and to avoid negative consequences (Proverbs 4:13–14). Those who ignore good sense are more likely to suffer and fail.

Addressing His disciples from a mountain, Jesus pronounced blessings on the poor in spirit; on those who mourn; on the meek; on those who hunger and thirst for righteousness; on the merciful; on the pure in heart; on the peacemakers; on those who are persecuted; and on those who are reviled, persecuted, and maligned for His sake (see Matthew 5:1–12).

In contrast, those who hate and reject God curse, threaten, and blaspheme. Words reveal the condition of the heart. Jesus told the hypocritical Pharisees, "You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. I tell you, on the day of judgment people will give account for every careless word they speak, for by your words you will be justified, and by your words you will be condemned" (Matthew 12:34–37).
