Ezekiel 47:1-2

Then he brought me back to the door of the house; and behold, water was flowing from under the threshold of the house toward the east, for the house faced east. And the water was flowing down from under, from the right side of the house, from south of the altar. He brought me out by way of the north gate and led me around on the outside to the outer gate by way of the gate that faces east. And behold, water was trickling from the south side.
