'Leaf' in the Bible

Then he brought me to the porch of the temple, and he measured each side pillar of the porch, five cubits on each side; and the width of the gate was three cubits on each side.

By the river on its bank, on one side and on the other, will grow all kinds of trees for food. Their leaves will not wither and their fruit will not fail. They shall bear every month because their water flows from the sanctuary, and their fruit will be for food and their leaves for healing.”
