Solomon
Proverbs 15:6BSB·traditional attribution

The house of the righteous has great treasure, but the income of the wicked is trouble.

Matthew Henry Presbyterian

Note, 1. Where righteousness is riches are, and the comforts of them: In the house of the righteous is much treasure. Religion teaches men to be diligent, temperate, and just, and by these means, ordinarily, the estate is increased. But that is not all: God blesses the habitation of the just, and that blessing makes rich without trouble.

John Gill Reformed Baptist

In the house of the righteous is much treasure,.... God sometimes blesses the righteous with great riches, as he did Abraham; or, however, if they have but little, it is better than the riches of many wicked; because they have what they have with a blessing, and they are content with it: and they have abundance of spiritual treasure; they have God for their portion...

Jamieson-Fausset-Brown Reformed

treasure--implying utility. trouble--vexation and affliction.
