In instructing Moses to take the census of the Israelites, the literal translation of what Hashem said is, “Elevate the heads of the children of Israel.”
The parsha Bamidbar precedes Shavuos, when we commemorate the giving of the Torah at Sinai. Prior to that great event, Hashem said to the Israelites, ‘You shall be unto Me a nation of priests, a sacred nation. You shall be a treasure to me from amongst all peoples.”
Although a person should be humble, one should never lose one’s sense of dignity and significance. There is a natural resistance to damaging something that is beautiful and precious. If we are aware of our own great value, we will never do anything that detracts from our greatness.
In taking a census, counting each individual, Moses was instructed to elevate each person. Each individual is a precious diamond.
