Genesis 2.9b:
The tree of life was in the midst of the garden, and the tree of the knowledge of good and evil. (ESV)
Revelation 2.7b:
‘To the one who conquers I will grant to eat of the tree of life, which is in the paradise of God.’ (ESV)
The word “paradeisos” used in the Greek language texts of the Bible, and translated into English as “paradise”, is borrowed from the ancient Persian language. This Persian word had the meaning of “walled park”, similar to the idea of a protected outdoors park area that we are familiar with.
In the verse above quoted from Genesis, the word “garden” is translated as “paradeisos” in the official Greek language translation of the Old Testament. This translation is known as the Septuagint. Therein was the tree of life. Likewise, the verse above quoted from the book of Revelation also uses the word paradise to refer to the place where the tree of life is located. So clearly the idea of paradise being the place of ideal existence and life is communicated in the Bible in the very beginning and at the end.
Bible scholars have referred to chapter 2 of Genesis as Paradise in the First Age, meaning that this was the original state of creation before Adam and Eve were deceived by the serpent. Chapter 2 and the first part of chapter 3 of Genesis communicate that the Garden of Eden was originally an ideal place of paradise.
