Provérbios 28:23 Midrash: Devarim Rabbah, Midrash Tanchuma Buber & Midrash Tanchuma

Another matter: “These are the words” – this is what the verse said: “One who rebukes a man will later find more favor than one with a slippery tongue” (Proverbs 28:23). Rabbi Pinḥas said in the name of Rabbi Ḥama bar Ḥanina: “One who rebukes” – this is Moses. “A man” – this is Israel, as it is stated: “You are My flock, flock of My pasture, you are man” (Ezekiel 34:31). What is “later [aḥarai]”? The Holy One blessed be He said: ‘In order to bring them after Me [aḥarai].’¹The word aḥarai can be a form of the word aḥarei, later, or aḥar, after, in which case aḥarai would mean “after me.” “Will…find…favor” – this is Moses, as it is written: “And you also found favor in My eyes” (Exodus 33:12). “Than one with a slippery tongue” – this is Bilam, who was slippery-tongued in his prophecies,²Bilam was slippery tongued in the manner in which he expressed his prophetic blessings of Israel, meaning that he flattered them excessively. and they [the Israelites] became haughty and stumbled in Shitim.³They grew haughty as a result of his blessings, and this led to their sinning with the daughters of Moav (see Numbers 25:1–3).
Another matter, “one who rebukes a man will later [aḥarai]” – Rabbi Yehuda ben Rabbi Simon said: What is aḥarai? The Holy One blessed be He said: ‘Moses, as it were, rebuked Me to follow Israel, and rebuked Israel to follow Me [aḥarai].’ To Israel, he said: “You have sinned” (Exodus 32:30). To the Holy One blessed be He, he said: “Why should Your wrath be enflamed against Your people?” (Exodus 32:11). What is “why”?⁴After all, this was stated in the immediate aftermath of the egregious sin of the Golden Calf. Rabbi Yitzḥak said: When Israel crafted the calf, the Holy One blessed be He sought to eradicate Israel’s enemies.⁵This is a euphemistic reference to Israel. Moses said to Him: ‘Master of the universe, this calf is useful to assist You.’ The Holy One blessed be He said to him: ‘In what way can it assist Me?’ Moses said to Him: ‘If You cause the rain to fall, it can cause the dew to rise; You can produce the winds, and it, the lightning.’ The Holy One blessed be He said to him: ‘Are you, too, straying after the calf?’⁶How can you ascribe any power to this inanimate object? Moses said before Him: ‘Then, “why should Your wrath be enflamed against Your people?”’⁷Moses argued that God should not appear to be jealous of an object that actually has no power (Maharzu; see also Etz Yosef).
To Israel he said: “You have sinned a great sin” (Exodus 32:30). Rabbi Yehuda ben Rabbi Simon said: To what is this matter comparable? To a king who became angry at his wife. He struck her and expelled her from his house. The groomsmen heard about this. They went to the king and said to him: ‘Oh, my lord, is this what a man does to his wife? What did she do to you?’ They went to her and said to her: ‘Until when will you anger him? Is it your first time? Is it your second time?’ Moses, too, when he went to the Holy One blessed be He, he said to Him: ‘“Why should your wrath be enflamed against your people,” are they not Your children?’ When he went to Israel, he said to them: ‘Until when will you anger Him? Is it your first time? Is it your second time?’ Likewise it says: “In the wilderness, in the Arava, opposite the Red Sea.”⁸Moses, in mentioning these places to the Israelites, was alluding to various occasions on which they angered God.

(Deut. 1:1:) THESE ARE THE WORDS THAT MOSES SPOKE. This text is related (to Prov. 28:23): THE ONE WHO REBUKES A PERSON WILL IN THE END FIND MORE FAVOR THAN THE ONE WITH A FLATTERING TONGUE. THE ONE WHO REBUKES A PERSON is Moses, since he rebuked Israel.⁷Deut. R. 1:2. (Ibid., cont.:) WILL IN THE END FIND MORE FAVOR <also refers to Moses>, since he found favor and good insight in the eyes of God and humanity. Thus it is stated (in Exod. 34:9): PLEASE, IF I HAVE FOUND FAVOR IN YOUR EYES, O LORD. (Prov. 28:23:) THE ONE WITH A FLATTERING TONGUE refers to Balaam, since he said to Israel (in Numb. 24:5): HOW BEAUTIFUL ARE YOUR TENTS, O JACOB; YOUR TABERNACLES, O ISRAEL. To what were they comparable? To a king's son, who had two guardians.⁸Gk.: paidagogoi. One loved him and the other hated him. The one who loved him warned him and said: My son, watch yourself, lest you make a transgression, since your father is judge; and if he hears that you have committed a transgression, even though he is your father, he will not show partiality to you. But the one who hated him said to him: Why are you depressed? Your father is king! Do as you desire. Be afraid of no mortal, for your father will not be upset with you. Similarly the son is Israel. The two guardians are Moses and Balaam. Moses loved them and said to them (in Deut. 11:16–17): TAKE HEED LEST YOUR HEART BE DECEIVED …; FOR THE ANGER OF THE LORD WILL BE KINDLED AGAINST YOU. Why? Because he is judge, as stated (in Deut. 4:39): SO KNOW THIS DAY AND TAKE TO HEART THAT THE LORD IS GOD. Balaam, however, said: Do not be afraid. You are his children. Do whatever you want, for he will not be upset with you. To all the nations he does whatever he decrees over them. Why? (Numb. 23:19:) GOD IS NOT A HUMAN, THAT HE SHOULD SPEAK FALSEHOOD. But in your case he said (ibid., cont.): HAS HE GIVEN HIS WORD WITHOUT ACTING <ON IT>? AND HAS HE SPOKEN <SOMETHING> WITHOUT FULFILLING IT? On this point Solomon cries out and says (in Prov. 27:6): THE WOUNDS OF A LOVED ONE ARE FOUND TO BE TRUSTWORTHY. This refers to Moses. (Ibid., cont.): AND THE KISSES OF AN ENEMY ARE PROFUSE. This refers to Balaam. (Deut. 1:1:) THESE ARE THE WORDS.

R. Samuel the son of Nahmani said that R. Jonathan stated: Whoever rebukes his companion for religious reasons earns a share of divine grace, as it is said: He that rebuketh a man shall in the end find more favor (Prov. 28:23). And furthermore a thread of divine favors will be drawn about him, as is said: He shall find favor. Scripture says: Mine ordinance shall ye do (Lev. 18:4). These are ordinances which, if they were not enumerated in the Torah, ought to have been. Scripture is speaking here of idolatry and blasphemy. My statutes shall ye keep, to walk therein (ibid.). These are the commandments against which the evil inclination contends, and against which the peoples of the earth rebel. These are: the wearing of garments made of wool and linen,¹²The law of shatnez; see Lev. 19:19. This commandment and all the following ones are disregarded as irrational by non-Jews. the eating of pig,¹³See Lev. 11:7. the spittle of a childless sister-in-law,¹⁴After one has refused to marry his brother’s widow under the law of levirate marriage; see Deut. 25:5–10. mixing seeds,¹⁵Deut. 22:9–11. stoning an ox for killing a human being,¹⁶Exod. 21:29. the heifer whose neck was broken,¹⁷Lev. 14:1–21. the bird sacrifice brought by a leper,¹⁷ a firstling of an ass,¹⁸Exod. 13:13. meat prepared in milk,¹⁹Exod. 23:9. and the goat that has been sent away (the scapegoat).²⁰Lev. 16:1–34. Azazel, the area where the scapegoat would perish. You might maintain that these are unimportant prohibitions. Hence Scripture says: I am the Lord: I have decreed them, and you art not permitted to repudiate them.
