1Then the man brought me back to the entrance of the temple, and I saw water flowing from under the threshold of the temple toward the east (for the temple faced east). The water was coming down from under the south side of the temple, south of the altar.
2Next he brought me out through the north gate and led me around the outside to the outer gate facing east, and there I saw the water trickling out from the south side.
— Ezekiel 47:1-2
