"Now the Lord God had planted a garden in the east, in Eden; there he put the man he had formed." NIV translation
God created a special place for man called the "Garden of Eden". Many people have tried to find out where this place is and there have been some really crazy suggestions (such as in the USA). Others have said that it is in Turkey, Iraq, or covered by the Persian Gulf. The simple fact of the matter is that God is unchanging and, through His word, we can see that this garden surrounds Jerusalem. The word that is translated "in the east" can also mean "prior to" and that is actually what it is talking about as we see that God "had planted" this garden.
"And the Lord God made all kinds of trees grow out of the ground - trees that were pleasing to the eye and good for food. In the middle of the garden were the tree of life and the tree of the knowledge of good and evil." NIV translation
Throughout the Bible, the number two is the number of witnesses and here we see two trees at the center of the garden. We do not know what kind of fruit these trees produced only that God caused all of the trees to grow. We know that the fruit of the tree of life could allow man to live forever. We also know that the fruit from the other tree gave men knowledge of sin.
"A river watering the garden flowed from Eden; from there it was separated into four headwaters." NIV translation
The source of the water is and was an underground spring located near the city of Jerusalem called the Gihon Spring and we find it mentioned throughout the Bible. This spring, then, split and formed the start of the four rivers that we will see. Throughout the Bible, water is a symbol of the Word of God and its power to sustain life. Jerusalem has always been the chosen city of God and life for all flows out of there; first in the waters that we see here and then in the person of Jesus Christ who was crucified there so that we may have life. God is a God of patterns and so this spring flowing out and becoming rivers that water the land is a picture of our Messiah.
"The name of the first is the Pishon; it winds through the entire land of Havilah, where there is gold. (The gold of that land is good; aromatic resin and onyx are also there.)" NIV translation
The first river is the Pishon which in Hebrew means "sandy land". Havilah is in what is now Saudi Arabia. This river reminds us that God's love flows through Jesus even to the most desolate areas and people that deny Him as the Son of God.
