2/4/10 Ezekiel sees a river coming from under the threshold of the temple, which faces east. This, of course, is the river that flows from the throne of God in Revelation. It travels across the inner court apparently to the south side of the altar. And it seems to be very shallow.
His guide takes him out of the north gate to outside of the temple wall and leads him to the east side of the outer wall where the river exits, continuing just south of the east gate. The river is still only ankle deep, then within a thousand cubits becomes knee deep, then waist deep, then over his head. It flows to the Dead Sea and purified the water there and turns the desert into a garden.
Fruit trees grow along the river and like the tree of life in Revelation it bears fruit every month, and its leaves are for healing.
The next part of the passage sections off where the tribes will live and points out that any aliens are to be included as native-born Israelites. The tribe they belong to is determined by where they live.
Finally, Ezekiel describes the city itself, located just south of the temple. Fitting the same description of the New Jerusalem it has three gates on each side for all twelve tribes. And it will be called “The Lord is There.” It is the capital of earth.
