Matthew Henry on Proverbs 13:7

Some who are really poor, trade and spend as if they were rich: this is sin, and will be shame, and it will end accordingly. Some that are really rich, would be thought to be poor: in this there is want of gratitude to God, want of justice and charity to others. There are many hypocrites, empty of grace, who will not be convinced of their poverty. There are many fearing Christians, who are spiritually rich, yet think themselves poor; by their doubts, and complaints, and griefs, they make themselves poor.
