Genesis 2:8-9 (NASB) The LORD God planted a garden toward the East, in Eden and there He placed the man whom He had formed. Out of the ground the LORD God caused to grow every tree that is pleasing to the sight and good for food; the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil.

Genesis 3:22 (NASB) Then the LORD God said, "Behold, the man has become like one of Us, knowing good and evil; and now, he might stretch out his hand, and take also from the tree of life and eat, and live forever"-

Genesis 3:24 (NASB) So He drove the man out; and at the east of the garden of Eden He stationed the cherubim and the flaming sword which turned every direction to guard the way to the tree of life.

Revelation 2:7 (NASB) 'He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will grant to eat of the tree of life which is in the Paradise of God.'

Revelation 22:1-2 Then he showed me a river of the water of life, clear as crystal, coming from the throne of God and of the Lamb, in the middle of its street. On either side of the river was the tree of life, bearing 12 kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations.

Revelation 22:14 (NASB) Blessed are those who wash their robes, so that they may have the right to the tree of life, and may enter by the gates into the city.

Revelation 22:19 and if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book.
