Break’s Over – Back to Work!By Rabbi Jack Abramowitz
After their installation, the Leviim were to work in the Mishkan, in lieu of the first-born sons. The job of the Leviim was to assist the kohanim in their sacramental duties. They would perform the service to atone for the people, so as not to incur Divine wrath.
The Levites were inaugurated into duty exactly as had been directed, then they got to work.
G-d told Moshe that the Leviim were to serve starting at age 25 and until age 50. They should be sure to stick to their assigned tasks and not do jobs exclusive to the kohanim.
