(Fol. 4b) MISHNA IX: He (R. Akiba) was wont to say: "The father influences his son in beauty, force, wealth, wisdom, longevity, and the reward to be bestowed on [his] posterity; and herein lies the end of destiny, as it is said (Is. 41, 4) He predetermines from the beginning of fate of the generations to come, (Fol. 5) and though it is said (Gen. 16, 13) They will enslave them and torture them for four hundred years, yet there is another passage (Ib. 16) The fourth generation will return again unto here."
MISHNA X: Furthermore, he used to say: "There are five things of a twelve month's duration — viz.. the punishment of the generation of the flood, that of Job, of the Egyptians, of Gog and Magog in the future time (Ez. 35, 2) and of the wicked in infernal regions, as it is said (Is. 66, 6) And it shall come to pass, that from one month to another; i.e., from the month he died next year, the same month renewed. R. Jochanan b. Nuri says that [the wicked in the infernum] lasts only from Passover till Pentecost, for it reads (Ib.) And from one Sabbath to another."
