Myśl Żydowska do Lamentacje Jeremiasza 4:3

According to the opinion that holds that after 4,291 years, the world will end, since he holds that we require at least 86 jubilees for the arrival of the Messiah and there is a need for another forty years until the king Messiah fully blossoms -- as it was at first when they went out of Egypt, that they overpowered their enemies after forty years (Numbers 14:33) to finish them off. And so after 4,291 years, the world will end. For 85 Jubilees are 4250 years, plus forty years for the blossoming of the Messiah, and then the world will end in the 41st year.
