47:1-23 These waters signify the gospel of Christ, which went forth from Jerusalem, and spread into the countries about; also the gifts and powers of the Holy Ghost which accompanied it, by virtue of which is spread far, and produced blessed effects. Christ is the Temple; and he is the Door; from him the living waters flow, out of his pierced side. They are increasing waters. Observe the progress of the gospel in the world, and the process of the work of grace in the heart; attend the motions of the blessed Spirit under Divine guidance. If we search into the things of God, we find some things plain and easy to be understood, as the waters that were but to the ankles; others more difficult, which require a deeper search, as the waters to the knees, or the loins; and some quite beyond our reach, which we cannot penetrate; but must, as St. Paul did, adore the depth, Ro 11. It is wisdom to begin with that which is most easy, before we proceed to that which is dark and hard to be understood. The promises of the sacred word, and the privileges of believers, as shed abroad in their souls by the quickening Spirit, abound where the gospel is preached; they nourish and delight the souls of men; they never fade nor wither, nor are exhausted. Even the leaves serve as medicines to the soul: the warnings and reproofs of the word, though less pleasant than Divine consolations, tend to heal the diseases of the soul. All who believe in Christ, and are united to him by his sanctifying Spirit, will share the privileges of Israelites. There is room in the church, and in heaven, for all who seek the blessings of that new covenant of which Christ is Mediator.

10. En-gedi … En-eglaim—En-gedi (meaning "fountain of the kid"), anciently, Hazazon-Tamar, now Ain-Jidy; west of the Dead Sea; David's place of refuge from Saul. En-eglaim means "fountain of two calves," on the confines of Moab, over against En-gedi, and near where Jordan enters the Dead Sea (Isa 15:8). These two limits are fixed on, to comprise between them the whole Dead Sea.

fish … according to their kinds—Jerome quotes an ancient theory that "there are a hundred fifty-three kinds of fishes," all of which were taken by the apostles (Joh 21:11), and not one remained uncaptured; signifying that both the noble and baseborn, the rich and the poor, and every class, are being drawn out of the sea of the world to salvation. Compare Mt 13:47, the gospel net; the apostles being fishermen, at first literally, afterwards spiritually (Mt 4:19).
