Мидраш к Бамидбар 14:37

… the prophets of Jerusalem were the first to sin, as it says “…for from the prophets of Jerusalem has falseness emanated to the whole land.” (Jeremiah 23:15) So too they were punished first and the rest did not escape, as it says “And a curse shall be taken from them…” (Jeremiah 29:22)

The spies have no share in the world to come, as it is said (Num. 14, 37) Died by the plague before the Lord; i.e., died — in this world; plague — in the world to come. The generation of the desert has no share in the world to come, as it is said (Ib. ib. 35) In this wilderness shall they die, and therein shall they be spent; etc., i.e., in the wilderness shall they die, in this world; and therein shall they be spent, in the world to come. So says R. Akiba. R. Eliezer, however, maintains: "Concerning them, Scripture says: (Ps. 1, 5) Gather together unto Me My pious servants, who make a covenant with Me by sacrifice. The congregation of Korah will not be restored [at the time of resurrection], as it is said (Num. 16, 33) And the earth closed over them, i.e., in this world; and they disappeared from the midst of the congregation — in the world to come." So says R. Akiba. R. Eliezer, however, says: "Concerning them, Scripture says: (I Sam. 2, 6) The Lord killeth and maketh alive; he bringeth down to the grave, and he bringeth up."

“For man too does not know his time; like fish that are caught in an evil trap, and like birds that are caught in the snare, so the sons of man are snared at an evil time, when it falls upon them suddenly” (Ecclesiastes 9:12).
“For man too does not know his time; like fish that are caught in an evil trap” – Rabbi Berekhya said: Is there an evil trap and a good trap? Reish Lakish said: This is a fish hook. That is what is written: “The people who spread the evil slander about the Land died [in the plague]” (Numbers 14:37). With what were they killed? The Rabbis and Rabbi Shimon bar Yoḥai, the Rabbis said: Diphtheria rose in their throats and they choked and died. Rabbi Shimon ben Yoḥai said: They died of their limbs falling off.⁷⁴This was the result of leprosy, one of the punishments for slander. Rabbi Yehuda ben Rabbi Simon said the reason of the Rabbis: “Evil trap” is stated here, and “evil” is written there; just as in the “evil” written here, the fish hook goes down into the throat of the fish and chokes it, so, too, the “evil” that is written there means that diphtheria rose in their throats and they died. Rabbi Berekhya said the reason of Rabbi Shimon ben Yoḥai: “Plague” is stated here, and plague is stated there: “This will be the plague” (Zechariah 14:12). Just as the plague stated there is with the falling off of limbs, so, too, the plague stated here is with the falling off of limbs.
Rabbi Berekhya said: You have a trap that traps in the sea and does not trap on dry land, [and there is a trap that] traps on dry land and does not trap in the sea.⁷⁵Yet, the term “evil trap” implies that it is effective both on land and at sea (Matnot Kehuna). Rather, this a hook that traps in the sea and traps on dry land, as it goes down into the throat of the fish and chokes it.⁷⁶It can also be used with bait on dry land to trap birds and animals. Rabbi Azarya and Rabbi Yonatan ben Rabbi Ḥagai [said] in the name of Rabbi Yitzḥak bar Maryon, in the name of Rabbi Ḥanina: You have a [type of] person who sins on earth but does not sin in Heaven,⁷⁷He sins in the area of interpersonal relations but not in ritual matters. [and there is a type of person who sins] in Heaven but does not sin on earth.⁷⁸He sins toward God, in ritual matters, but does not sin in the areas of interpersonal relations. However, one who speaks evil speech sins in Heaven and on earth, as it is stated: “They set their mouth against Heaven; their tongue walks across the land” (Psalms 73:9). Rabbi Elazar said: We find that they walk in Heaven,⁷⁹They boast as though the walk in Heaven. but their tongue walks on the earth. What is the reason that “they set their mouth against Heaven?” [It is because] “their tongue walks across the land.” Rabbi Yoḥanan said: A person speaks evil speech only after he denies the fundamental belief in God, as it is stated: “Who have said: With our tongue we will prevail; our lips are our own. [Who is master over us?]” (Psalms 12:5). Rabbi Yitzḥak said: “Ponder this well, you who have forgotten God” (Psalms 50:22) – these are they who speak evil speech, as it is stated: “Who have said: With our tongue we will prevail; our lips are our own. [Who is master over us?]” (Psalms 12:5).
