Wealth and riches shall be in his house - The Septuagint and the Vulgate render this, "glory and riches shall be in his house." The word, however, properly means riches or wealth, and the two terms are used apparently to convey the idea that wealth or property in "varied forms" would be in his house; that is, not merely gold and silver, but all that was understood to constitute wealth - variety of garments, articles of furniture, etc. This promise is of the same nature as that of the previous verse. It pertains to a general truth in regard to the influence of religion in promoting prosperity. Compare the notes at 1-Timothy 4:8.
And his righteousness endureth for ever - That is, The effects of it shall be transmitted from age to age in the prosperity, the respectability, the wealth, the happiness of his descendants. It travels on from age to age, and blesses distant generations.

Wealth and riches shall be in his house - This is often the case: a godly man must save both time and money. Before he was converted he lost much time, and squandered his money. All this he now saves, and therefore wealth and riches must be in his house; and if he do not distribute to the necessities of the poor, they will continue to accumulate till they be his curse; or God will, by his providence, sweep them away. Both צדקה tsedakah and δικαιοσυνη are often used to signify, not only justice and righteousness, but also beneficence and almsgiving; and this is most probably the meaning here. See Psalm 112:9.

(b) Wealth and riches [shall be] in his house: and his righteousness endureth for ever.
(b) The godly will have abundance and contentment, because their heart is satisfied in God alone.

Wealth and riches shall be in his house,.... In his family; if not possessed by him, yet by his posterity: though rather this signifies spiritual riches, the riches of grace, the unsearchable riches of Christ, durable riches and righteousness; seeing it is connected with an everlasting righteousness, as in the next clause.
And his righteousness endureth for ever; he is not hurt by his temporal riches, as others are, the prodigal, the covetous, and formal professor; he continues the good and righteous man he was, notwithstanding his riches. Some understand this of his liberality with his riches, as alms deeds are sometimes called righteousness; see Psalm 112:9 though it rather intends either inherent righteousness, the new man which is created in righteousness, the inward principle of grace which always continues; or the righteousness of Christ imputed to him, which is an everlasting one.

Righteousness - The fruit or reward of his righteousness, which is God's blessing upon his estate.
