Why should the sons of Kohath die, if they touch any of the holy things?

Numbers 4:15 (ESV)

15 And when Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, as the camp sets out, after that the sons of Kohath shall come to carry these, but they must not touch the holy things, lest they die. These are the things of the tent of meeting that the sons of Kohath are to carry.

As with the death of Nadab and Abihu (Leviticus 10:1–20), this shows the complete and utter holiness of God, who is taking residence amongst a sinful people. The Levites are reminded that he will be served on his terms, not theirs.
