Their delight is in the law of the Lord, and on his law they meditate day and night. They are like trees planted by streams of water, which yield their fruit in its season, and their leaves do not wither. In all that they do, they prosper.
Psalm 1:2-3

Beside the torrent on either bank fruitful trees of every kind will grow. Their leaves will not wither, nor will their fruit fail, they will bear fruit early every month, for the water for them flows from the sanctuary; their fruit is for food and their leaves for healing.
Ezekiel 47:12

Then the angel showed me the river of the water of life, sparkling like crystal, flowing from the throne of God and of the Lamb down the middle of the city’s street.

On either side of the river stood a tree of life, which yields twelve crops of fruit, one for each month of the year. The leaves of the tree are for the healing of the nations.
Revelation 22:1-2

Happy is he who has found wisdom, he who has acquired understanding,
for wisdom is more profitable than silver, and the gain she brings is better
than gold! She is more precious than red coral, and none of your jewels can compare with her. In her left hand are riches and honour. Her ways are pleasant ways and her paths all lead to prosperity. She is a tree of life to those who grasp her, and those who hold her fast are safe.

By wisdom the Lord laid the earth’s foundations and by understanding he set the heavens in place; by his knowledge the springs of the deep burst forth and the clouds dropped dew.
Proverbs 3:13-20
