The priest will take some of the blood of the sin offering and place it on the doorpost of the temple, on the four corners of the ledge of the altar, and on the doorpost of the gate of the inner court.

Then he brought me back to the entrance of the temple. I noticed ¹  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.
