Genesis 20:1 From there Abraham journeyed toward the territory of the Negeb and lived between Kadesh and Shur; and he sojourned 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 Abimelech in a dream by night and said to him, “Behold, you are a dead man because of the woman whom you have taken, for she is a man’s wife.” Now Abimelech had not approached her. So he said, “Lord, will you kill an innocent people? Did he not himself say to me, ‘She is my sister’? And she herself said, ‘He is my brother.’ In the integrity of my heart and the innocence of my hands I have done this.” Then God said to him in the dream, “Yes, I know that you have done this in the integrity of your heart, and it was I who kept you from sinning against me. Therefore I did not let you touch her. Now then, return the man’s wife, for he is a prophet, so that he will pray for you, and you shall live. But if you do not return her, know that you shall surely die, you and all who are yours.”
After the destruction of Sodom and Gomorrah, Abraham removed from the grove of Mamre at Hebron to the south country, hardly from the same fear as that which led Lot from Zoar, but probably to seek for better pasture. Here he dwelt between Kadesh (Genesis 14:7) and Shur (Genesis 16:7), and remained for some time in Gerar, a place the name of which has been preserved in the deep and broad Wady Jurf el Gerr (i.e., torrent of Gerar) about eight miles S.S.E. of Gaza, near to which Rowland discovered the ruins of an ancient town bearing the name of Khirbet el Gerr. Here Abimelech, the Philistine king of Gerar, like Pharaoh in Egypt, took Sarah, whom Abraham had again announced to be his sister, into his harem, – not indeed because he was charmed with the beauty of the woman of 90, which was either renovated, or had not yet faded (Kurtz), but in all probability “to ally himself with Abraham, the rich nomad prince” (Delitzsch). From this danger, into which the untruthful statement of both her husband and herself had brought her, she was once more rescued by the faithfulness of the covenant God. In a dream by night God appeared to Abimelech, and threatened him with death (מת הנּך en te moriturum) on account of the woman, whom he had taken, because she was married to a husband. (Keil and Delitzsch)
Twenty years before, Abraham had acted in the same way in Egypt, and Pharaoh had rebuked him, but sent him away with large presents. We learn from this chapter, Genesis 20:13, that the false representation which twice brought them into trouble was habitual with the two; nor does Abraham ever seem conscious that he was acting in it wrongfully. To us it seems cowardly, in one who had so many men trained to battle, thus to expose his wife to danger; and to have recourse to deceit, at the very time when such abundant revelations were being made to him, also shows an apparent want of faith in God. But Holy Scripture neither represents its heroes as perfect, nor does it raise them disproportionately above the level of their own times. Its distinguishing feature rather is that it ever insists upon a perpetual progress upwards, and urges men onward to be better and holier than those that went before. Abraham was not on the same high spiritual level as a Christian ought to be who has the perfect example of Christ as his pattern, and the gift of the Holy Ghost for his aid; and the fact that God rescued him and Sarah from all danger in Egypt may have seemed to him a warrant that in future difficulties he would have the same Divine protection. (Ellicott)
It is hard for us to know the purpose of Abimelech in taking Sarah. It could have been lust or a means of alliance that was custom at the time. I think we can take from this;
- God is in control
- God is ever-present
- God is all powerful
- Guard your faith
- Stand firm in your faith against the customs of the culture
- Innocence does not mean we have not committed a sin or a wrong
- Praise God that we have been given the Holy Spirit to give us discernment and guide our paths
