Midrash sur Job 5:26

Our Rabbis were taught: One who dies suddenly, he is said to have died an abrupt death; if the death was preceded by one day's sickness, it is a hastened death. R. Chanina b. Gamaliel, however, says: "The latter case is termed a plague-death, as it is said (Ez. 24, 16) Son of man, behold, I will take away from thee the desire of thy eyes by a sudden death (plague); and it is written again (Ib. 18) And when I had spoken unto the people in the morning, my wife died in the evening." When one has been sick for two days and dies, it is considered a hurried death; after three days, it is considered a rebuked death; after four days, it is a frowned death; but if one dies after having been sick five days, it is considered an ordinary death. Said R. Chanin: "What is the Biblical passage to prove this? (Deut. 31, 14) And God said unto Moses, Hehn Karbu yamecha lamuth (Behold, thy days approach that thou must die). Hehn means one in Greek; karbu (in the plural) is two; yamecha (in the plural) is also two, which make a total of five." Death at the age of fifty is Kareth; at fifty-two, is the age at which Samuel of Ramah died; at sixty, an ordinary death. Said Mar Zutra: "Whence is this deduced? (Job 5, 26) Thou wilt go in a ripe age, unto the grave; the word Bakelach (ripe age) equals the number sixty." Seventy is called an old age; eighty, an age of uncommon vigor, as it is written (Ps. 90, 10) Our days are seventy years, and if by uncommon vigor they be eighty. Rabba, however, said: "From fifty to sixty it is Kareth; and the reason why this is not stated in the Baraitha is because of the honor of Samuel." When R. Joseph arrived at the age of sixty, he gave an entertainment to the Rabbis, for he said: "I have passed the years of Kareth." Said Abaye to him: "It is true that the master has passed the years of Kareth, but has then the master already passed the days of Kareth?" Whereupon R. Joseph answered him: "Be content with one half in your hand." R. Huna died suddenly, which caused the Rabbis great worry. A couple of sages of Hadaeb taught them: "It was stated [regarding a sudden death] that only when the deceased has not reached the age of eighty; but if he has, it is, on the contrary, considered a death caused by a kiss."
