Ezekiel 47:1

He brought me back to the door of the temple; and behold, waters flowed out from under the threshold of the temple eastward, for the front of the temple faced toward the east. The waters came down from underneath, from the right side of the temple, on the south of the altar.

Afterward he brought me again unto the door of the house; and, behold, waters issued out from under the threshold of the house eastward: for the forefront of the house stood toward the east, and the waters came down from under from the right side of the house, at the south side of the altar.
