The word is used again later in a story linked to something important: it’s the word used when Sarah drives out Hagar.
And she said to Abraham, “Get rid of that slave woman and her son, for that woman’s son will never share in the inheritance with my son Isaac.”
Genesis 21:10 (NIV)
While we wrestle with Sarah’s unkindness and Abe’s foolishness and Hagar’s slave-status, there’s something that Paul says later about this story that we have to understand. These characters represent something.
For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise.
Galations 4:22-23 (NIV)
There’s so much talk about “works” and “faith,” and Paul links these concepts to slavery and freedom as it relates to God’s promise to us.
When Sarah demands that Abe “get rid of” Hagar and the boy, she is using this same word of “banishing” as Genesis 3.
The link should be viewed through an eternal lens: God is banishing the slavery of works and our own attempts at attaining status and relationship from the garden. The Garden is Holy.
He’s not kicking US out. He’s kicking out the works of the flesh.
How do we know this?
Because if you read the text closely, God only banishes Adam from the garden, and not Eve, who represents Life. The spirit. The one through whom God promises to bring redemption. Not through through One born of the flesh, but born of the spirit.
And the Lord God said, “The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.” So the Lord God banished him from the Garden of Eden to work the ground from which he had been taken. After he drove the man out, he placed on the east side of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life.
Genesis 3:22-24 (NIV)
