What does Genesis 20:1 mean?
Abraham moves his great household from the region around Mamre south toward the border of the land of Canaan. We're not told the reason for this move. They settle in Gerar, between Kadesh and Shur. Gerar was south of Gaza, near the coast of the Mediterranean Sea, and within the borders of the Promised Land. Abraham travelled often throughout the land of Canaan during his lifetime.The events of this chapter echo those of Genesis chapter 12, where Abraham succumbed to fear during his travels. There, Abraham lied about being married to Sarah, resulting in her being taken by the ruling Pharaoh as a wife. Only after God's intervention was the situation resolved. Here, strangely, Abraham seems to make exactly the same fearful mistake. Rather than simply acting in faith, and being honest, Abraham and Sarah once again try to scheme their way towards a goal. And, as happened in other cases, the scheme backfires (Genesis 12:13–15).
