The New Living Translation is a good version for checking long lists - Numbers 2

The math indicates the numbers tend the way he says, and then it is a matter of combining that with the shape of the setup of the Tabernacle and exactly how the various encampment were placed.

It is at least plausible.

I have never seen it before, the other version I saw placed the tribes side by side.

Given that the longest side and the opening of the Tabernacle faced the sunrise, like the Temple did, it also shows a fascinating "shadow of a cross" within the Tabernacle area too.

So there is at least one cross, if not two, in the entire setup.

And what struck me once I saw Zola Levitt Ministries' 1980s program about the Tabernacle together with a Bible scholar, was that when seen as a model, it indeed looks like a Pesach/Easter/Passion play in itself, with the various rooms, items and elements reminiscent of that weekend.

Dr. Golan Broshi of One For Israel Ministries is also one of many "teacher voices" and commentators and theologians that speak about the many layers of fullfillment of the Bible. One understanding and pass-through surpassing another, a grander design being revealed, ever more complete understanding.

God's designs are wonderful and contain ever new depths and surprises - and this also clearly indicates that there are VISUAL HINTS to be found for the close observer incorporated in the design of the layout.

Opening up ever new levels of faith too! Yes, it is marvelous in our eyes! Halleluiah!

"The heavenly blueprint" as Wolfgang Simson calls it.
