Midrasz do Sędziów 2:7

R. Simon b. Pazi said in the name of R. Joshua b. Levi, who spoke in the name of bar Kappara: "Whoever sheds tears upon the death of an upright person, the Holy One, praised be He! will number and store it in His treasure, as it is said (Ps. 56, 9.) My wandering hast Thou well numbered; put Thou my tears into thy bottle; behold they are numbered by Thee." R. Juda in the name of Rab said: "Whoever is slow to mourn the death of a Chacham (scholar) is destined to be buried alive, as it is said (Jos. 24, 30.) And they buried him on the border of his inheritance at Timnath Serach, which is on the mountain of Ephraim, on the north side of Mt. Ga'ash. i.e., Ga'ash (storm). We infer from this that the mountain stormed at them (Israel) and wished to destroy them [because they did not mourn the death of Joshua] . R. Chiya b. Abba in the name of R. Jochanan said: "Whoever is slow to mourn the death of a scholar will not live long. This is a retaliation, as it is said (Is. 27, 8.) In measure, by driving him forth, thou strivest with him." The following objection was raised to R. Jochanan by R. Chiya b. Abba: "And the people served the Lord all the days of Joshua, and all the days of the elders that lived many days after Joshua (Judg; 2, 7.) [Hence they were not punished.]" "Thou Babylonian!" said R. Jochanan to him, "it says many days but not many years." According to this interpretation, the passage (Deu. 11, 21.) In order that your days may he multiplied, and the days of your children, would also mean days and not years. When it alludes to a blessing, it is different. R. Chiva b. Abba in the name of R. Jochanan said also: "If one brother dies, all the remaining brothers should feel anxious [examine their deeds]. If a member of a society should die, let the whole society become anxious. According to some, this is so only when the most important one among them should die, and according to others, only when the least important one should die."
