Moshe’s role in erecting the Tabernacle
Moshe already had his own “personal Tabernacle,” the “tent of Meeting,” which was outside the camp (Ki Sissa 33:7). Therefore, he did not need to be involved in constructing the Tabernacle, which was primarily for the Divine Presence to dwell also among the Jewish people. Nevertheless, God told Moshe that he should be involved, and He gave him the task of erecting the Tabernacle.
This teaches us that a person cannot only busy himself with his own spiritual development and Torah study. He needs also to be involved in helping others, just like God who wanted Moshe to be involved in the Tabernacle, not just as a spiritual leader and mentor, but also, “with his hands.”
