Jer 5:4

“The strong in soul are spoken of with approval. For also among the Greeks the strong and the greatness of the rational soul are continually named. For whenever anyone throws himself into great deeds, has worthwhile objectives, always considers what is right and how he can live in accordance with right reason, wishing not to know anything abject and small, such a person has in the soul the strong and the great. The others, then, the ones the Word disparaged since they were poor, did not hear, the prophet said; they did not hear for this reason: since they were poor. I will go to the strong and speak to them, and if it is so that the blessed person is meant in the saying the ears of those who hear one is blessed if he should ever meet a strong and great listener.”

“Truly, slander humiliates a person, and slander troubles the poor person. The evil of slander is so great that it brings down both the perfect person … from his height, and the poor person, that is, the one who lacks great learning, as it seems to the prophet, who says, "Perhaps they are poor … therefore they will not hear. I will go to the great ones," meaning by "the poor" those lacking in intelligence, and here, of course, those not yet made orderly in the inner person or having attained to the perfect measure of their age. These, the proverb says, are troubled and made to waver.”

“Paul says about those who live in piety and prosperity, "I thank God that in every way you were enriched in him with all speech and all knowledge." And to those who are impious, the blessed Jeremiah says, "Maybe they are poor. For this reason, they could not hear the word of the Lord." Do you see that he calls poor those who have distanced themselves from piety? Therefore, God is merciful to those who sin because they are spiritually poor, and he places demands on those who act justly because they are spiritually rich. To the former he gives freely, on account of their poverty. From the latter he collects with great care, on account of their wealth of piety. That which he does to the righteous and to sinners, he does to both the rich and the poor.”

“(Vers. 4, 5.) But I said: Perhaps they are poor and foolish (or they were unable) and ignorant of the way of the Lord, the judgment of their God. Therefore, I will go to the noble ones, and I will speak to them: for they have known the way of the Lord, the judgment of their God. Here, the poor and the noble ones, he does not speak of poverty and wealth, but compares the people to the rulers. And the meaning is this: Seeing the stubbornness of the unfaithful people, and that with hardened face, he did not want to receive instruction, this is the reasoning I had with myself: Perhaps the common people, who are ignorant of God, cannot know the teachings, and therefore it is excusable, because due to their lack of knowledge of God, they are unable to know the commandments. Therefore, I will go to the priests and those who preside over the people, and I will speak to them. For they have known the will of the Lord and understand His judgment. However, this is said in the manner of one who is uncertain, according to the Gospel saying: 'I will send my son, perhaps they will respect him' (Matthew 21:37), so that through the ambiguity of the sentence and the suspension of words, the free will of man might be shown.”

“"Well-off" refers to the priests and the teachers of the law; "poor" refers to the rest, insofar as they did not possess the wealth of divine knowledge. Yet he accuses both of lawlessness, proceeding in this way, "They all alike broke the yoke, they snapped the bonds." It was not without purpose the prophet said this. Instead, since the Lord promised lovingkindness, provided he found someone "doing justice and seeking faith," he explains that though he went looking, as he was commanded to do, he found they had all broken the yoke of the law.”
