Issac lied to Abimelech. Fearful of his host, the king of the Philistines, Issac told him that Rebekah was his sister, not his wife. Abimelech caught Issac in his lie, scolded him, and eventually drove Issac and his clan away (Genesis 26).

This incident mirrors Abraham’s lie about his wife, Sarah, to Pharaoh in Egypt (Genesis 12).

So I wonder, did Issac come up with this scheme on his own? More likely, he heard stories growing up in the family tents about how Abraham outwitted Pharaoh and grew rich. The apple doesn’t fall far from the tree. Be careful the stories you tell your children.
