Matthew Poole and continuators on Psalms 112:3

3 Wealth and riches shall be in his house : and his righteousness endureth for ever.

Possessed by him whilst he lives, and continued in his family after his death.

i. e. The fruit or reward of his righteousness, which is Gods blessing upon his estate: for the work is oft put for the reward of it, as in the Hebrew, Levit. 19. 13. Iob 7. 2. Psal. 109. 20. And righteousness may be here taken for his bounty or charity, as it is below v. 9. and as this Hebrew word is frequently taken.
