Numbers 8:26 - Exposition

Shall minister … to keep the charge, and shall do no service. The word "charge" (Hebrew, mishmereth ) seems to signify the care of the furniture and belongings of the tabernacle, while "service" means the laborious work of transport, or of preparing sacrifice. The duties of the Levite over fifty were in fact honorary, given to him probably for his own sake, that he might have some place and post in the house of God. This careful provision for those who should attain the age of fifty shows that the commandment was designed for the promised land rather than for the wilderness.
