John 5 King James Version (KJV)
5 After this there was a feast of the Jews; and Jesus went up to Jerusalem.
2 Now there is at Jerusalem by the sheep market a pool, which is called in the Hebrew tongue Bethesda, having five porches.
3 In these lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water.
4 For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had.
For an angel went down] The miracle of this pool was granted to the Jews, partly to strengthen them in the true worship of God under the persecution of Antiochus, in the cessation of prophecy; partly to retain them in their religious course of sacrificing to the true God, against the scoffs of the Romans (that were now their lords). Such a virtue being given to that water, wherein their sacrifices were wont to be washed. See a more sovereign bath than this, Zechariah 13:1; an ever-flowing and over-flowing fountain, not for one at once, as here, but for all that come, they may wash and be clean, wash and be whole.
