Gen 2:9 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.
Gen 2:15-17 Then the Lord God took the man and put him into the garden of Eden to cultivate it and keep it. 16 The Lord God commanded the man, saying, "From any tree of the garden you may eat freely; 17 but from the tree of the knowledge of good and evil you shall not eat, for in the day that you eat from it you will surely die."
Gen 3:22-24 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" — 23 therefore the Lord God sent him out from the garden of Eden, to cultivate the ground from which he was taken. 24 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.
Gal 3:13 Christ redeemed us from the curse of the Law, having become a curse for us — for it is written, "CURSED IS EVERYONE WHO HANGS ON A TREE" —
Rev 22:1-5 Then he showed me a river of the water of life, clear as crystal, coming from the throne of God and of the Lamb, 2 in the middle of its street. On either side of the river was the tree of life, bearing twelve kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations. 3 There will no longer be any curse; and the throne of God and of the Lamb will be in it, and His bond-servants will serve Him; 4 they will see His face, and His name will be on their foreheads. 5 And there will no longer be any night; and they will not have need of the light of a lamp nor the light of the sun, because the Lord God will illumine them; and they will reign forever and ever.
Rev 22:14 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.
