The man went away, and told the Jews that it was Jesus who had made him well.

 When Jesus arrived in Jerusalem he was apparently alone; there is no mention of his disciples. He found his way to a famous pool. Its name was either Bethesda, which means House of Mercy, or more likely, Bethzatha which means House of the Olive. The better manuscripts all have the second name, and we know from Josephus that there was a quarter of Jerusalem actually known as Bethzatha. The word for pool kolumbethron ( G2861) , which comes from the verb kolumban ( G2860) , to dive. The pool was deep enough to swim in. The passage we have put in brackets is not in any of the greatest and best manuscripts and was probably added later as an explanation of what people were doing at the pool. Beneath the pool was a subterranean stream which every now and again bubbled up and disturbed the waters. The belief was that the disturbance was caused by an angel, and that the first person to get into the pool after the troubling of the water would be healed from any illness from which he was suffering.
