Adam Clarke on Ezekiel 47:12

Shall grow all trees for meat, whose leaf shall not fade - A description that suits the righteous, who are still producing -

1. The fruits of faith.

2. The fruits of the Spirit.

3. The fruits of love to God, obedience to his holy will, and love to all men. Benevolence, mercy, charity, kindness, etc.

The leaf thereof for medicine - See Rev 22:1-5. Even the leaves, the holy profession of the righteous, is a spiritual medicine. Righteousness is thus encouraged in the world. The profession points out the salvation, as it shows the nature and sufficiency of that salvation; for a just creed contains all the articles of the Christian faith.
