In Revelations we read that the city will have a river that is banked with fruit trees which give a different fruit every month.
Also the leaves are used by the nations for healing...could this be some kind of treatment to reduce the radiation from the end time wars???
New International Version (©1984) rev 2:22
down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations.
