Eden is an ancient word, and was the name of two different biblical places and one person. The name appears 20 times in 19 different verses in Scripture.
Eden was the name of an area in the pre-Flood world and was part of the original Creation. At that time, the world was a beautiful and perfect paradise. God planted a garden in Eden. It was a real place, not mythological. It was here that God put Adam and Eve, the first two humans. They lived and worked there (Genesis 2:8-17) until they sinned against God. Their sin brought evil into themselves, separating them from their holy Creator. God forced Adam and Eve to leave the garden. He wisely placed Cherubims at the garden’s east entrance to prevent human access to the Tree of Life which evidently could have circumvented the physical death to which they were condemned.
There has been much speculation about Eden’s location on the globe. See: Has the Garden of Eden ever been found?
Among almost all nations, there are traditions of the original innocence of humans in the Garden of Eden. This was the “golden age” to which the Greeks looked back. Men then lived a “life free from care, and without labor and sorrow. Old age was unknown; the body never lost its vigour; existence was a perpetual feast without a taint of evil. The earth brought forth spontaneously all things that were good in profuse abundance.”
Eden was also the name of a market (or region) where the merchants of Tyre obtained richly embroidered material and other things (Ezek. 27:23). It is probably this same place that is mentioned in 2 Kings 19:12, and Isaiah 37:12, as the name of a region conquered by the Assyrians.
Eden was the name of a son of Joah, and one of the Levites who assisted in reforming the public worship of the sanctuary in the time of Hezekiah (2 Chronicles 29:12).
