"Your children shall be under your fathers. Rabbi Elazar, son of Rabbi Yosei, said: In the future, each and every person from Israel will have children like those of Egypt, as it is said, "Your children shall be under your fathers." And how many were our fathers when they left Egypt? Six hundred thousand. Rabbi Abbahu said: Do not be surprised, for a hen once laid two eggs in one day and one egg the next day. This is what is written, "For as the days of a tree shall be the days of My people" (Isaiah 65:22)."
