A fountain shall come forth of the house of the Lord, etc… Viz., the fountain of grace in the church militant, and of glory in the church triumphant: which shall water the torrent or valley of thorns, that is, the souls that before, like barren ground brought forth nothing but thorns; or that were afflicted with the thorns of crosses and tribulations.
3:19. Egypt shall be a desolation, and Edom a wilderness destroyed: because they have done unjustly against the children of Juda, and have shed innocent blood in their land.
3:20. And Judea shall be inhabited for ever, and Jerusalem to generation and generation.
Judea—and Jerusalem… That is, the spiritual Jerusalem, viz., the church of Christ.
3:21. And I will cleanse their blood, which I had not cleansed: and the Lord will dwell in Sion.
