Midrash su Salmi 95:11

The generation of the desert has no share, etc. Our Rabbis were taught: The generation of the desert had no share in the world to come, as it is written (Num. 14) In the wilderness shall they be spent, etc., i.e., in the wilderness, refers to this world; and therein shall they die, refers to the world to come, and it is also written (Ps. 95, 11) So that I swore in My wrath, that they should not enter into My rest. Thus says R. Akiba. R. Eliezer, however, says: "They have a share in the world to come, as it is said (Ib. 50, 5) Gather unto Me My pious servants. But how shall the verse I swore in My wrath be explained? I retract from it because it was sworn while I was in anger." R. Joshua b. Karcha says: "The verse cited by R. Eliezer was said only concerning the future generations. Gather together unto Me My pious servants, refers to the righteous who are to be found in every generation. Who make a covenant, refers to Chananiah, Mishael, and Azariah, who delivered themselves to [be thrown into] the kiln. Sacrifice, refers to R. Akiba and his colleagues, who had delivered themselves to be slain because of the words of the Torah." R. Simon b. Menasia says: "They (the generation of the desert), will have a share in the world to come, as it is said (Isa. 35, 10) And come to Zion with song." Rabba b. b. Chana said in the name of R. Jochanan: "R. Akiba has departed from his [usual] kindness (i.e., his harsh opinion does not agree with hirality shown elsewhere), for it is said (Jer. 2, 2) I remember unto thee the kindness of thy youth, the love of thy espousals, thy going after Me in the wilderness, through a land that is not sown. Now since we see that even their descendants will benefit from their reward, how much more so they themselves!"

One verse states (Bamidbar 7:89): "And when Moses came to the tent of meeting to speak with him, etc." and another, (Shemoth 40:35): "And Moses could not come to the tent of meeting!" This is resolved by (Shemoth 40:35): "for the cloud rested upon it." Say: Whenever the cloud was there, Moses did not enter. When the cloud departed, he entered and spoke with Him. R. Yossi Haglili says: It is written (I Kings 8:11): "And the Cohanim were not able to stand to minister because of the cloud, for the glory of the L–rd filled the house of the L–rd" — whence it is seen that the angels were given license to destroy (all who would approach). And, similarly, (Shemoth 33:22): "And I shall cover you with My 'palm' until I have passed" — whence it is seen that the angels were given license to destroy. And, similarly, (Psalms 95:11): "So I swore in My wrath that they would not enter My rest" — When My wrath abates, they will enter My rest."

“Even in your thought do not curse a king, and in your bedrooms do not curse the wealthy, as a bird of the heavens will carry the sound, and a winged one will tell the matter” (Ecclesiastes 10:20).
“Even in your thought do not curse a king” – Rabbi Yehuda ben Rabbi Simon said: The Holy One blessed be He says to a person: Because I have given you intellect beyond that of the animal, the beast, and the birds, you curse and blaspheme before me? I gave you eyes and [the animal] eyes, you have ears and it has ears, you have hands and it has hands, you have feet and it has feet, you have a mouth and it has a mouth, he is like the beasts that perish [nidma].⁸⁶This is an adaptation in the singular of Psalms 49:21. The verse compares people to beasts, but the midrash reads it as implying a difference between people and animals, that animals cannot speak. Nidma means nothing other than silence; I have silenced it before you.⁸⁷Unlike people, animals cannot speak. See the honor that I have afforded you. But you do not understand all this goodness, “man does not understand the honor” (Psalms 49:21).
Another matter: “Even in your thought do not curse a king” that is in your generation, “and in your bedrooms do not curse the wealthy” – do not curse the wealthy of your generation. “As a bird of the heavens” – Rabbi Yirmeya ben Elazar said: This is the raven, by means of bird divination.⁸⁸The king or wealthy people might find out what you said from the ravens, by means of bird divination. “And a winged one will tell the matter” – because the wall has ears.
Another matter: “Even in your thought do not curse a king” – the King of the world; “and in your bedrooms do not curse the wealthy” – the wealthy One of the world. “As a bird of the heavens will carry the sound” – Rabbi Yehoshua of Sikhnin [said] in the name of Rabbi Levi: There are some sounds that are for good and there are some sounds that are for evil. [There are] sounds for good, as it is stated: “The Lord heard the sound of your words…they have done well in everything that they spoke” (Deuteronomy 5:24). Ḥiyya bar Ada and bar Kappara: Ḥiyya bar Abba said: For good [hatava], as in the preparation of [hatavat] the incense. Bar Kappara said: For good, as in the cleaning of [hatavat] the lamps. [There are] sounds for evil, as it is stated: “The Lord heard the sound of your words, and He was enraged and took an oath…” (Deuteronomy 1:34).
Rabbi Abbahu [said] in the name of Rabbi Taḥalifa his father in law: It is written: “As I took an oath in My wrath” (Psalms 95:11) – the Holy One blessed be He said: I took an oath in My wrath, but then I recanted; “that they⁸⁹The generation of the wilderness, which left Egypt. will not enter My place of rest” (Psalms 95:11) – they will not enter this resting place,⁹⁰The Land of Israel but they will enter another resting place.⁹¹The World to Come Rabbi Beivai said in the name of Rabbi Yehoshua ben Levi: [This is analogous] to a king who was angry at his son and expelled him from his palace and took an oath that he would not allow his son to enter the palace. What did he do [once he reconsidered]? It was [already] built; he dismantled it and rebuilt it, and brought his son into it. He thereby brings his son in and [still] fulfills his vow. So too, the Holy One blessed be He said: I took an oath in My wrath and recanted. They will not enter this resting place, but they will enter another resting place.
“And a winged one will tell the matter” – Rabbi Bon said: When a person sleeps, the body tells the soul [what it has done], the soul [tells it] to the spirit, the spirit to the angel, the angel to the cherub, and the cherub to the winged one. Who is that? It is the seraph. The seraph will bring the matter and tell it before He who spoke and the world came into being.
Another matter: “Even in your thought do not curse a king” – do not curse a king who is before you. “And in your bedrooms do not curse the wealthy” – a prominent person in your locale. “As a bird of the heavens will carry the sound” – the Holy One blessed be He said to David: Would you not say: “All my enemies shall be ashamed and frightened” (Psalms 6:11)? Who were your enemies? Was it not Saul? Would you not say: “On the day that the Lord rescued him from the hand of all his enemies and from the hand of Saul” (Psalms 18:1)?⁹²Thus, you cursed the king I appointed over Israel. David said: Master of the universe: Do You calculate them for me as intentional transgressions? Consider them as unwitting transgressions [shegagot] for me. That is what is written: “A meditation [shigayon] by David, a song that he sang to the Lord concerning the words of Kush the Benjamite (Psalms 7:1).⁹³Kush the Benjamite is a reference to Saul (see Moed Katan 16b).
Another matter: “Even in your thought do not curse a king” – this is Moses, as it is stated: “There was a king in Yeshurun” (Deuteronomy 33:5). “And in your bedrooms do not curse the wealth” – this is Moses. From where did Moses become wealthy? It was from the residue of the tablets. Rabbi Ḥanin said: He discovered a quarry of sapphires in his tent, and from that Moses became wealthy, as it is stated: “Carve for you two tablets of stone…” (Exodus 34:1), its carvings will be for you.
