It turns out that Manasseh represents (in type) the Father and the replica of the Father which is the Holy Spirit. This is explained in Genesis 1 when God separated the waters under the firmament (FIRMament = Son) from the waters above the firmament. Explained in the NT when Christ declared, Don’t you know that I am in the Father and the Father is in me? It’s the whole reason we have a half tube of Manasseh on one side of Jordan, and one half on the other side. To the east represents the Father in us, CROSS over Jordan and into the promise, that’s us in the Father.
