In the house of the righteous is much treasure (chosen; see on Proverbs 27:24). The good man's store is not wasted or wrongly used, and is blest by God: and therefore, whether absolutely much or little, it is safe, and it is sufficient.
In a spiritual sense, the soul of the righteous is filled with graces and adorned with good works. Septuagint, "In the houses of the righteous is much strength;" plurima fortitudo, Vulgate. But in the revenues of the wicked is trouble.
Great revenues acquired by wrong or expended badly bring only trouble, vexation, and ruin upon a man and his family. Septuagint, "The fruits of the wicked shall perish." Spiritually, the works of the wicked cause misery to themselves and others.
