Compass Directions in the Bible
Genesis 12 that tells us that the Oak of the Moreh was at the sacred center between Bethel and Ai (an east-west axis). Deborah's Palm was between Ramah and Bethel (a north-south axis). The Tree of Life was in the middle of the garden. If the sacred center is the place where the east-west axis and the north-south axis intersect, we have the image of the Cross.
