In entry “Salvation Part II” I make mention of a three-level Kingdom.  I came upon this today at Aish while investigating today’s Torah portion:
 

THREE LEVITE FAMILIES 

Although these four points are important, we can also suggest another approach in understanding God’s expectation of us when it comes to peace. The beginning of this week’s Torah portion focuses on the tribe of Levi, which is composed of three main families: Kehat, Gershon, and Merari. Based on the Shem MiShmuel and the Netivot Shalom, we can understand these three families as representing three spiritual levels.

The family of Kehat represents the highest, most righteous level. Their role is to carry the Holy Ark (Rashi on Numbers 4:4) – the highest component of the Tabernacle. The importance of this task underscores their lofty spiritual level.

The family of Gershon represents the middle level. They carry the curtain that divides the Holy of Holies from the rest of the Sanctuary (Numbers 4:25). One side of the curtain is close to the intense sanctity of the Holy of Holies, while the other side is not. We could suggest that this curtain hints to the spiritual level of an average person, who fluctuates between moments of intense devotion and moments of feeling less connected to the Divine.

The family of Merari represents the lowest level. They carry the beams and pillars of the Sanctuary (Numbers 4:31), the weight of which can be burdensome. This physical weight represents the heaviness of the lowest spiritual level.

  

Exodus 19:4-6 You yourselves have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to myself. Now IF you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, you will be for me a kingdom of priests and a holy nation. These are the words you are to speak to the Israelites.”

1 Peter 2:9, “You are a chosen people, a royal priesthood, a holy nation, a people belonging to YHWH, that you may declare the praises of Him who called you out of darkness into His wonderful light.”

 

 

That makes quite a statement.
