Ezekiel 47:1-2

1Then he brought me back to the entrance of the temple. I noticed that water was flowing from under the threshold of the temple toward the east (for the temple faced east). The water was flowing down from under the right side of the temple, from south of the altar.

2He led me out by way of the north gate and brought me around the outside of the outer gate that faces toward the east; I noticed that the water was trickling out from the south side.
