Exodus ends with an exploration of the meaning of our Shabbat cycle alongside the tabernacle's completion. The Israelites all brought contributions to the tabernacle until Moses commanded them to stop and observe Shabbat, after which the sequence would begin again. In every generation, each of us does what we can to build for the generation to follow, who will pick up where we leave off. Following this train of thought, Rabbi Ingber suggests that not everything you want to see in the world can happen through you alone - we must pass that torch over to future generations to carry.
