When Jesus saw him lying there, and knew that he had been sick for a long time, he asked him, "Do you want to be made well?"
      Now this is all the account we have of this standing miracle; it is uncertain when it began and when it ceased. Some conjecture it began when Eliashib the high priest began the building of the wall about Jerusalem, and sanctified it with prayer; and that God testified his acceptance by putting this virtue into the adjoining pool. Some think it began now lately at Christ's birth; nay, others at his baptism. Dr. Lightfoot, finding in Josephus, Antiq. 15. 121-122, mention of a great earthquake in the seventh year of Herod, thirty years before Christ's birth, supposed, since there used to be earthquakes at the descent of angels, that then the angel first descended to stir this water. Some think it ceased with this miracle, others at Christ's death; however, it is certain it had a gracious signification. First, it was a token of God's good will to that people, and an indication that, though they had been long without prophets and miracles, yet God had not cast them off; though they were now an oppressed despised people, and many were ready to say, Where are all the wonders that our fathers told us of? God did hereby let them know that he had still a kindness for the city of their solemnities. We may hence take occasion to acknowledge with thankfulness God's power and goodness in the mineral waters, that contribute so much to the health of mankind; for God made the fountains of water,Revelation 14:7. Secondly, It was a type of the Messiah, who is the fountain opened; and was intended to raise people's expectations of him who is the Sun of righteousness, that arises with healing under his wings. These waters had formerly been used for purifying, now for healing, to signify both the cleansing and curing virtue of the blood of Christ, that incomparable bath, which heals all our diseases. The waters of Siloam, which filled this pool, signified the kingdom of David, and of Christ the Son of David (Isaiah 8:6); fitly therefore have they now this sovereign virtue put into them. The laver of regeneration is to us as Bethesda's pool, healing our spiritual diseases; not at certain seasons, but at all times. Whoever will, let him come.
