“When you acquire a Jewish bondsman, for six years he shall work and in the seventh year he shall go free...”

-Mishpatim 21:2

“Six years,” an allusion to the 6000 years of the world’s normative existence, “he shall work”.

That is, during this period, in the present time of this existence, there is the opportunity of serving G‑d with Torah and mitzvot. By virtue of this service:

“In the seventh year,” i.e., in the seventh millenium, “he shall go free...”-we shall be released and be free of all the obstacles and hindrances that presently are dominant in the world, and we shall merit the sublime manifestations of the Messianic future.
