In the house of the righteous is much treasure: but in the revenues of the wicked is trouble.
– Proverbs 15:6
[T]he righteous and the wicked are both gaining. The gain of the righteous is stored up as treasure, or wealth. The point of the first phrase is that through wisdom, the gains made by righteousness are a blessing (Proverbs 8:21; 21:20). These blessed gains come through honest and hard work (Proverbs 10:4; 21:5). The word for revenues means income, or produce. The word for trouble means to roil water, i.e., to stir up or disturb. The wicked pursue gains hastily and craftily, so they come with much trouble (Proverbs 20:21; 21:5-7; 28:22).
