They are also an allusion to the tradition that this universe will continue for 6,000 years before it will experience a metamorphosis of 1,000 years after which the עולם הבא (next world) will be ushered in. The 1,000-year interval symbolizes the concept of the Sabbath.
But don’t forget this one thing, loved ones—that with Yahweh one day is like a thousand years, and a thousand years like one day. Yahweh is not slow in keeping His promise, as some consider slowness. Rather, He is patient toward you—not wanting anyone to perish, but for all to come to repentance. But the Day of Yahweh will come like a thief. On that day, the heavens will pass away with a roar and the elements will melt in fervent heat, and the earth and all its works will be exposed.
AND I appointed the eighth day also, that the eighth day should be the first-created after my work, and that the first seven revolve in the form of the seventh thousand, and that at the beginning of the eighth thousand there should be a time of not-counting, endless, with neither years nor months nor weeks nor days nor hours.
The final war will cause the nations to realize the oneness of God, and they will come to Jerusalem to seek the Messiah.
