There is a river with trees growing along the bank. Think of the river as Christ and the trees as Christians. Together we can feed and heal the world. Maybe Ezekiel had this in mind.

Ezekiel 47:12
Along the bank of the river, on this side and that, will grow all kinds of trees used for food; their leaves will not wither, and their fruit will not fail. They will bear fruit every month, because their water flows from the sanctuary. Their fruit will be for food, and their leaves for medicine.”
