Yahweh/Gods' agents
To implement the "righteousness of Gods' law".
The true priest of Yah protect the holiness of God, and execute His righteous judgement, and keep people from defiling themselves and His holy congregation.
The Levitical priesthood is a pattern to understand the Judaical priesthood.
Let's examine
Numbers 2:1-13 and compare our priesthood to the priesthood of shadow.
