Ezekiel 47:1-2

1And he brought me back 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 was toward the east: and the waters came down from under, from the right side of the house, on the south of the altar.

2Then brought he me out by the way of the gate northward, and led me round by the way without unto the outer gate, by the way of the gate that looketh toward the east; and behold, there ran out waters on the right side.
