Proverbs 15:6

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. Or, if there be not much of this world's goods, yet where there is grace there is true treasure; and those who have but little, if they have a heart to be therewith content, and to enjoy the comfort of that little, it is enough; it is all riches. The righteous perhaps are not themselves enriched, but there is treasure in their house, a blessing in store, which their children after them may reap the benefit of. A wicked worldly man is only for having his belly filled with those treasures, his own sensual appetite gratified (Psa 17:14); but a righteous man's first care is for his soul and then for his seed, to have treasure in his heart and then in his house, which his relations and those about him may have the benefit of. 2.
