Prov 22:16

“He who oppresses the poor, etc. It is evident that the rapacious, those who take from the poor and also those who seem to justly possess what they have, lose everything equally, when, in the examination of the strict judge, they receive punishment for the things they have done. But even those who slander their brother, poor in spirit, by detracting from his virtues, in order to increase the wealth they desire, that is, the glory of human praise, appearing holier by his reproach; rightfully such a slanderer loses whatever good action he seemed to possess and will remain void of the fruit of virtues in the end. This is the furthest point reached by the title of the Proverbs of Solomon, set above; from which it is proven he assumed a new manner of speaking so that what he says appears not as if teaching someone else but as if reasoning alone with himself. Indeed, the first verse of these Proverbs is, A wise son makes a father glad, but a foolish son is a grief to his mother. This is the last verse to which we have explained down to here. From here, he returns to the previous manner of speaking to address a specific person to whom he gives instruction; which so begins, Incline your ear, etc. He sets a most beautiful beginning of the new speech, so that one whom he teaches, he bids to incline his ear to listen and his heart to understand what wise men say.”
