They will be like trees growing beside a stream-- trees with roots that reach down to the water, and with leaves that are always green. They bear fruit every year and are never worried by a lack of rain.
Fruit trees will grow all along this river and produce fresh fruit every month. The leaves will never dry out, because they will always have water from the stream that flows from the temple, and they will be used for healing people.
These people are filthy minded, and by their shameful and selfish actions they spoil the meals you eat together. They are like clouds blown along by the wind, but never bringing any rain. They are like leafless trees, uprooted and dead, and unable to produce fruit.
