Притчи 10:7

Thus, as Pro 10:6 says how it goes with the righteous and the wicked in this life, so this verse tells how it fares with them after death: The memory of the righteous remains in blessings, And the name of the godless rots. The tradition regarding the writing of זכר with five (זכר) or six points (זכר) is doubtful (vid., Heidenheim in his ed. of the Pentateuch, Mer Enajim, under Exo 17:14); the Cod. 1294 and old printed copies have here זכר. Instead of לברכה, יברך might be used; the phrase היה לברכה (opp. היה לקללה, often used by Jeremiah), subordinate to the substantival clause, paraphrases the passive, for it expresses a growing to something, and thus the entrance into a state of endurance. The remembrance of the righteous endures after his death, for he is thought of with thankfulness (צל''ז = זכר צדיק לברכה, the usual appendix to the name of an honoured, beloved man who has died), because his works, rich in blessing, continue; the name of the godless, on the contrary, far from continuing fresh and green (Psa 62:1-12 :17) after his departure, becomes corrupt (רקב, from רק, to be or to become thin, to dissolve in fine parts, tabescere), like a worm-eaten decayed tree (Isa 40:20). The Talmud explains it thus, Joma 38b: foulness comes over their name, so that we call no one after their name. Also the idea suggests itself, that his name becomes corrupt, as it were, with his bones; the Mishnah, at least Ohaloth ii. 1, uses רקב of the dust of corruption.

Both the just and the wicked, when their days are fulfilled, must die. Between their bodies in the grave thee is no visible difference; between the souls of the one and the other, in the world of spirits, thee is a vast difference, and so there is, or ought to be, between their memories, which survive them. I. Good men are and ought to be well spoken of when they are gone; it is one of the blessings that comes upon the head of the just, even when their head is laid. Blessed men leave behind them blessed memories. 1. It is part of the dignity of the saints, especially those who excel in virtue and are eminently useful, that they are remembered with respect when they are dead. Their good name, their name with good men, for good things, is then in a special manner as precious ointment, Ecc 7:1. Those that honour God he will thus honour, Psa 112:3, Psa 112:6, Psa 112:9. The elders by faith obtained a good report (Heb 11:2), and, being dead, are yet spoken of. 2. It is part of the duty of the survivors: Let the memory of the just be blessed, so the Jews read it, and observe it as a precept, not naming an eminently just man that is dead without adding, Let his memory be blessed. We must delight in making an honourable mention of good men that are gone, bless God for them, and for his gifts and graces that appeared in them, and especially be followers of them in that which is good. II. Bad men are and shall be forgotten, or spoken of with contempt. When their bodies are putrefying in the grave their names also shall rot. Either they shall not be preserved at all, but buried in oblivion (no good can be said of them, and therefore the greatest kindness that can be done them will be to say nothing of them), or they shall be loathsome, and mentioned with detestation, and that rule…

10:7 the name of a wicked person rots away: In ancient Israel, as is still true today in the Middle East, honor and shame were powerful motivators.
