Genesis 20:1-14 (NIV):
Now
Abraham moved on from there into the region of the Negev and lived between
Kadesh and Shur. For a while he stayed in Gerar, And Abraham said of Sarah his
wife, “She is my sister.” And Abimelech king of Gerar sent and took Sarah. But
God came to Abimelek in a dream one night and said to him, “You are as good as
dead because of the woman you have taken; she is a married woman.” Now
Abimelek had not gone near her, so he said, “Lord, will you destroy an innocent
nation? Did he not say to me, ‘She is my sister,’ and didn’t she also say, ‘He
is my brother’? I have done this with a clear conscience and clean hands.” Then
God said to him in the dream, “Yes, I know you did this with a clear
conscience, and so I have kept you from sinning
against me. That is why I did not let you touch her. Now return the man’s wife, for he is a prophet, and he will
pray for you and you will live. But if you do not return her, you may be sure
that you and all who belong to you will die.” Early the next morning Abimelek
summoned all his officials, and when he told them all that had happened, they
were very much afraid. Then Abimelek called Abraham in and said, “What have you
done to us? How have I wronged you that you have brought such great guilt
upon me and my kingdom? You have done things to me that should never be
done.” And Abimelek asked Abraham, “What was your reason for doing this?” Abraham
replied, “I said to myself, ‘There is surely no fear of God in this place, and
they will kill me because of my wife.’ Besides, she really is my sister, the
daughter of my father though not of my mother; and she became my wife. And when
God had me wander from my father’s household, I said to her, ‘This is how you
can show your love to me: Everywhere we go, say of me, “He is my brother."
Then Abimelek brought sheep and cattle and male and female slaves and gave them
to Abraham, and he returned Sarah his wife to him.
Four categories of sin are present here. There
was inadvertent sin because Abimelek did not know Sarah was Abraham's wife.
There was hidden sin because Abimelek lusted after Sarah in his heart, and he
did so willfully. There was also the potential for great sin. We know this
because God told Abimelek that if he followed through with his desires and had
sexual relations with Sarah, God would not only kill Abimelek but he would also
wipe out his entire tribe. Even Abimelek acknowledged the "great guilt"
which Abimelek alleged that Abraham had brought upon him and his kingdom. As
further evidence of the depth of the sin, God had closed the wombs of all the
women of Abimilek's tribe while Sarah was in Abimilek's household so that they
could not bear children. Gen. 20:17-18.
What
I find to be the most interesting part of this text is where God tells Abimelek
that "I have kept you from sinning against me. That is why I did not
let you touch her." We are not told precisely how this happened, but
apparently God had arranged Abimelek's affairs in such a way that even though
he desperately wanted to sleep with Sarah, he just couldn't get to it. It could be that he
was distracted with other matters, or maybe he was sick or had suffered some
debilitating injury. In any event, God did not let him sin in this way.
