“Let no one think that this was said only recently and that it was spoken of by the philosophers before it was mentioned in the gospel. For the philosophers, that is to say, Aristotle and Theophrastus, as also Zeno and Hieronymus, certainly lived before the time of the gospel, but they came after the prophets. Let them rather think how long before even the names of the philosophers were heard of, both of these [Aristotle and Theophrastus] seem to have found open expression through the mouth of the holy David; for it is written, "Blessed is the man whom you instruct, O Lord, and teach him out of your law." We find elsewhere also, "Blessed is the man who fears the Lord, he will rejoice greatly in his commandments." We have proved our point as regards knowledge, the reward for which the prophet states to be the fruit of eternity, adding that in the house of the one who fears the Lord or is instructed in his law and rejoices greatly in the divine commandments "is glory and riches; and his justice abides for ever and ever." He has further also in the same psalm made statements about good works, that they gain for an upright man the gift of eternal life. He speaks thus: "Blessed is the man who shows pity and lends; he will guide his affairs with discretion, surely he shall not be moved for ever, the righteous shall be in everlasting remembrance." And further, "He has dispersed, he has given to the poor, his justice endures forever."”

“"Glory and riches shall be in his house" [Psalm 112:3]. For his house is his heart; where, with the praise of God, he lives in greater riches with the hope of eternal life, than with men flattering, in palaces of marble, with splendidly adorned ceilings, with the fear of everlasting death. "For his righteousness endures for ever:" this is his glory, there are his riches. While the other's purple, and fine linen, and grand banquets, even when present, are passing away; and when they have come to an end, the burning tongue shall cry out, longing for a drop of water from the finger's end. [Luke 16:24]”

“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 Psa 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.”
