The Lignum vitae's clover-shaped base has a passage from Revelation 22:2, "And on both sides of the river was the tree of life, producing twelve fruits, giving its fruits every month: the leaves of the tree for the healing of the nations." The diagram's tree picture can be interpreted as an example of this text...
...or it could be a representation of the Holy Trinity. The tree of life appears in Genesis 2:9 and 3:22 where it serves as a symbol of God's creative power and provision for humanity. It will continue to appear throughout Scripture as an image used by various authors to represent God.
In Judaism, the tree of life is mentioned several times. It appears in Ezekiel 47:12 as part of a vision of the restored Jerusalem. There are also references to the tree of life in Zechariah 14:8 and Malachi 3:23. It is important to note that in Judaism the tree of life is associated with healing and life rather than judgment as it is in Christianity.
In Christianity, the tree of life first appears in the book of Genesis. When God creates man he tells him that he may live forever if he chooses to eat from the fruit of the tree of knowledge of good and evil. If we look at the tree within the context of Revelation 22 we can see that it is representing Jesus Christ.
The "pure river of water of life" that flows "out of the throne of God" is mentioned in Revelation 22. The river seems to feed two trees of life, one "on either side of the river" that "produce twelve kinds of fruits" and whose "leaves were for the healing of the nations" (v.1-2).
These trees are probably not ordinary trees but rather representations of the twelve tribes of Israel. According to the book of Genesis, God gave Abraham specific instructions about where to locate his descendants after he had chosen them as a nation from among all the peoples on earth. These descendants became known as the 12 tribes of Israel.
Abraham's children included both men and women when they married outside of their own tribe. They also included slaves who had been captured in battle or purchased from other countries. There are examples of both male and female slaves being brought into the family business or household service.
Israel was a representative democracy, so each member of the community had an equal voice in government. Power was divided between a king or queen who led by example and represented everyone else in leadership roles, and a parliament made up of members from each of the tribes. Each member of the parliament had a role to play in making decisions for the tribe. They could vote on issues before them or offer suggestions.
Tribes had the ability to control their own destiny by choosing which direction they wanted to go in relation to religion and culture.
2 refers to the Tree of Life. Despite the fact that it isn't the first time it has been discussed. The tree of life, as mentioned in Genesis, represents God's provision for immortality in the Garden of Eden. It was destroyed when Adam and Eve disobeyed God.
Here are some other passages where trees are mentioned:
Genesis 2:9 - "And out of the ground made he man."
Deuteronomy 32:13 - "The oak, the pine, the cypress, the myrtle, any large tree which the LORD chooses."
Ezekiel 47:1-12 - "In the middle of the street of the holy city they will surely take the branches of green olive trees and with them will cover the shame of the priest. And they will say: This is the sin offering which the master requires."
Revelation 11:1 says that two of every kind of bird will be allowed into the New Jerusalem. Trees provide food for many different kinds of birds. So by killing these animals, we are actually killing trees too!
Finally, Revelation 22:2 tells us that the Tree of Life represented God's provision for immortality. Since humans cannot live forever without dying, this shows that Jesus is the only way to heaven.
