'Tree' in the Bible

"'Let all who have ears give heed to what the Spirit is saying to the Churches. To him who overcomes I will give the privilege of eating the fruit of the Tree of Life, which is in the Paradise of God.'

After this I saw four angels standing at the four corners of the earth, and holding back the four winds of the earth so that no wind should blow over the earth or the sea or upon any tree.

And they were forbidden to injure the herbage of the earth, or any green thing, or any tree. They were only to injure human beings--those who have not the seal of God on their foreheads.

On either side of the river, midway between it and the main street of the city, was the Tree of Life. It produced twelve kinds of fruit, yielding a fresh crop month by month, and the leaves of the tree served as medicine for the nations.

Blessed are those who wash their robes clean, that they may have a right to the Tree of Life, and may go through the gates into the city.

and that if any one takes away from the words of the book of this prophecy, God will take from him his share in the Tree of Life and in the holy city--the things described in this book.
