What pool did Jesus tell the blind man to wash in?

Answer: Siloam

Jesus told him, 'Go, wash in the Pool of Siloam.' The man went, washed, and came home seeing.

“Then He told him, “Go, wash in the Pool of Siloam” (which means “Sent”). So the man went and washed, and came back seeing.”— John 9:7 (BSB)
