In Parashat Naso, we encounter a census and the delineation of various divisions of the responsibilities of the Kohanim who are to dissassemble, carry, and reassemble the Mishkan on the nation's journey through the wilderness. Ramban comments on the special mention of the family of Merari among the Kohanim, who are charged with a special task. We can all seek to remember to work on knowing our mission and destiny to fulfill our tasks to our best abilities within our own lives.
