Covenant Conversation

There is a deeper message in Parshat Tetzaveh - the principle of the separation of powers, which opposes the concentration of leadership into one person or institution. All human authority needs checks and balances if it is not to become corrupt. In particular, political and religious leadership (keter malchut and keter kehunah) should never be combined. Moses wore the crowns of political and prophetic leadership, Aaron that of priesthood. The division allowed each to be a check on the other.
