New Defender's Study Bible Notes
22:1 pure river. The primeval river emerging from Eden (Genesis 2:10) seems to have been a type of this eternal river proceeding from the throne of the Lamb. Like the former river, this also will probably part into four directions, watering the whole city and on out into the whole earth. Since there will be no sea, there will be no rain. This wonderful river of water of life, however, will surely support an abundance of vegetation everywhere—with enough water for the whole world, and with none wasted. Presumably, the Lord will continue to create an unending supply of water from His throne for all these needs.
