2 Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness.
“What is good.” … Abraham did not have good things because he was rich but because he used his riches well. And Lazarus, who later rested on Abraham’s bosom, did not suffer the pains of sickness and bear evils on the grounds of natural necessity; rather, he was pursued by evil people who thought truly good things were to be found in the world. Hence, the rich man of noble standing received good things in his life—which were food to him who thought they were good. Conversely, about Lazarus it is not said, “He received his own bad things in his life,” but rather “he received evil things in his life,” since they were not evils to him who suffered but seemed that way to others. Blessed Job has offered us an example of each, since he neither in good things nor in bad was overcome but endured all things with firm equanimity.
(Verse 2, 3.) Hear me, you who listen, and eat what is good, and your soul will delight in abundance. Incline your ear and come to me; listen, and your soul will live. And I will make an everlasting covenant with you, the sure mercies of David. And I will establish for you an everlasting covenant, holy and faithful to David. Lest anyone think these are hearsay of the flesh, not of the mind, to whom the divine word encourages them to listen, promising them not the goods of the flesh but of the soul. For, he says, if you listen to me, you will eat the good things of the earth (Isaiah 1:19). Or of the one who says: I am the good shepherd (John 10:11). And your soul will delight in good things and in richness. Therefore, the goods that are promised to the soul are not riches, and bodily health, and worldly honors, which even the philosophers call indifferent, that is, neither good nor bad, and vary according to the quality of the users; but they must believe in those things to which God encourages us: Turn away from evil and do good (Psalm 37:27). But if the soul is said to be good, then honesty and virtues are also said to be good. Therefore, not poverty, bodily infirmity, and low social status should be considered as evils, but rather all vices that are truly bad. In conclusion, Abraham was not considered good because he was wealthy, but because he made good use of his wealth (Genesis XIII). And Lazarus, who later rested in his bosom, did not endure evils because he suffered the torment of diseases in poverty, but he attained true good through the evils that were considered in the world. And so that rich man, clothed in purple, received his good things in his life, which were good to him, who thought them good (Luc. XVI), and of Lazarus it is not said on the contrary: He received his evil things in his life; but he received his evil things in his life, which were not evil to him, who suffered, but seemed evil to others. The blessed Job gives us an example of both things, who was not conquered in the good things or the evils of the world, but endured everything with equal strength of mind (Job. II). Therefore, Solomon prays to God: Do not give me riches and poverty. But establish for me what is necessary and sufficient for my sustenance, so that I may not become satiated and speak falsely, saying, 'Who sees me?' or 'I am needy and therefore become a thief and swear falsely by the name of the Lord' (Prov. X, 8, 9). But if he prays for this, that he may neither possess riches nor poverty, but only the necessary sustenance, of which the Apostle also says, 'Having food and clothing, with these we shall be content' (I Tim. VI): it is evident that riches and poverty, health and sickness, pleasure and torment, are not inherently good or evil, but become good or evil depending on the diversity of those who endure them. Therefore the Lord promises not a thousand riches, abundance of wealth, and luxurious food, and corpulence of the body, and bean dishes and stuffed turtles, mead, wine, and the beauty of wives, the offspring of bees, but those delights to which he mystically provokes us, saying: Delight yourself, or enjoy delights in the Lord, and he will give you the desires of your heart (Psalm 36:4); and elsewhere: I believe I shall see the good things of the Lord in the land of the living (Psalm 26:13); and in another psalm: Bless the Lord, O my soul, and let all that is within me bless his holy name. Who fills your desire with good things (Ps. 102:1, 5). Finally, he adds: Hear me, and your soul will live (Isaiah 55:3). The promise of all good things is eternal life. But if you wish to hear and your soul will live forever, I will make with you an everlasting covenant, the faithful mercies of David. Concerning which the same Psalmist sings: I will sing the mercies of the Lord forever. In generation and generation I will announce your truth (Ps. 88:1, 2). And so that we may know what these mercies are, he explains in the following discourse: Once I swore in my holiness: if I lie to David, his seed will endure forever, and his throne will be like the sun before me, and like the moon, perfect forever, and a faithful witness in heaven. He is called faithful for this reason, because he has fulfilled the promises. For this reason, the Seventy translated it as 'the holy and faithful things of David' (Acts 13:34), which can be understood as strong and firm. That is, faithful is he in all his commandments: confirmed for ever and ever (Ps. CX, 8). And in another place: God is faithful, and there is no iniquity in him (Deut. XXXII, 4). And the apostle Paul says: If we deny him, he remains faithful: he cannot deny himself (II Tim. II, 13). And in another place, writing to Timothy: Faithful is the saying, and worthy of all acceptance (I Tim. XV). But this pact, which the Lord promises, will not be brief and of one time, as it was for the people of the Jews, but it will remain forever, so that the true David may come, and what has been promised from the person of God may be fulfilled in the Gospel: I have found David my servant, with my holy oil I have anointed him (Ps. LXXXVIII, 21). Whose hand he placed in the sea, and his right hand in the rivers. Whom, according to Ezekiel, David, who has been sleeping for many centuries, calls his servant and shepherd, saying: I will raise up for you one shepherd, my servant David (Ezekiel 34:23).
How can they purchase, yet receive gifts without paying? Well, because we accept the payment in faith from Christ, and we pay for none of these things with short-term or perishable goods. For it says, “I said to my Lord, ‘You are my Lord since you have no need of goods from me.’ ” By way of gifts and honor to Christ we offer to Christ the confession of faith in him. So without money and payment comes this drink and bountiful gift of spiritual charisms. For what could we offer and what price could we pay for such a drink? For those drinking the living water are those enriched with grace through the Holy Spirit through participation in him and purchasing this through faith, since they are sharers of the wine and suet, that is, of the holy body and the blood of Christ.
Behold what [Isaiah] has shown here, before indicating the road of righteousness. For it is thanks to all-holy baptism that “we are justified freely,” according to the divine apostle: “by his grace through the redemption that is in Christ Jesus.” It is this the prophetic text likewise allows [us] to understand: “And all that have no money, go and buy, and eat and drink wine and fat without money or price.” The divine Scripture often calls righteousness “money.” “The oracles of the Lord are pure oracles; as silver tried in the fire, proved in a furnace of earth.” As for those who live with iniquity, “call them rejected silver, for the Lord has rejected them.” …Here he rejected the sacrifices of the law.… The prophetic text teaches that these sacrifices gave no nourishment to the soul.
