Afterward he brought me again unto the door of the house; and, behold, waters issued out from under the threshold of the house eastward: for the front of the house faced toward the east, and the waters came down from under the right side of the house, at the south side of the altar.

Waters. These waters are not to be understood literally, (for there were none such that flowed from the temple) but mystically of the baptism of Christ, and of his doctrine and his grace; the trees that grow on the banks are Christian virtues; the fishes are Christians, that spiritually live in and by these holy waters; the fishermen are the apostles, and apostolic preachers; the fenny places, where there is no health, are such as by being out of the Church are separated from these waters of life. (Challoner)
It is not probable that real water or fishes were found, ver. 9. But this must be explained of the Church and of baptism, in a higher and more proper sense. (Worthington)
Joel, (iii. 18.) before the captivity, and Zacharias, (xiv. 8.) after that event, speak of fountains as still to appear, and of course not in either temple, though Pilate made aqueducts for the purpose, (Josephus, Jewish Wars ii. 13.) which Tacitus, (An. v.) Maundrel, (p. 148.) and others mention. But the prophets allude not to them, but to Christ, the fountain of water springing up unto life eternal, John iv. 14., and vii. 38. (Calmet)
Villalpand understands it of waters brought into the temple to wash the victims; but it seems to refer more to the grace and doctrine of Christ. (Menochius)
