Ezek 47:1-2

Water Flowing from the Temple 1Then he brought me back to the entrance of the temple; there, water was flowing from below the threshold of the temple toward the east (for the temple faced east); and the water was flowing down from below the south end of the threshold of the temple, south of the altar.2Then he brought me out by way of the north gate, and led me around on the outside to the outer gate that faces toward the east; and the water was coming out on the south side.
