Ezekiel 47:1-2

1Then he brought me back to the door of the House. Behold, water was flowing out from under the threshold of the House eastward—for the front of the House faced east. The water was flowing down from under the right side of the House, south of the altar.

2He brought me out by way of the north gate and led me around outside by the way of the outer gate, the way of the gate looking east. Behold, water was trickling out from the right side.
