Ezechiela 35:2 Midrasz: Ein Yaakov (Glick Edition)

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."
