Judah, Rueben, Ephraim and Dan . . .huh. What'dya know about that.
The north point symbolizes up, and its an eagle, and Dan is the judge. What do you always say about elevated places?

Also in the zodiac the eagle has the serpent in its talons, seems to me that might be telling us how to overcome the serpent.
The rising sun(Son) comes from the East. The daystar arises in our hearts. A star will rise out of the tribe of Judah. On the temple mount looking out from the HOH toward the east is Mount of Olives where Jesus was crucified and Ascended, also the Shekinah moved there right before the destruction of the temple. The high priests camped to the east too.
The man on the south point which is the right hand if God is sitting on His throne the ark of the covenant, looking east, Son of my Right hand.
Our works (ox) are behind us, and our kingship (lion) lies ahead of us. Our works push us toward the east toward the kingship. Kingship is the goal not the works.
If the gospels are each one of the heads, that leaves out the fifth gospel, ACTS. The major story of acts (to me) is Pauls revelation of Christ IN him. Paul was the 13th apostle, just as there were 13 tribes, with Joseph being doubled to continue the outer shell, since Levi was called out of the outer encampment to camp around the tabernacle, then out of the families of Levites Aarons family was the one who could go into the HOH. Always calling out, just as the overcomers are called out. I see Paul/ACTS/overcomers representing the actual tabernacle itself, which is the central point of the whole Bible, Christ in you the hope of glory.
The encampment is the first dividing line, outside that is the nations, the outer encampment is body. Levites with inner encampment is Soul. Aaron/high priests is spirit.
