6 So Isaac went on living in Gerar; 7 And when he was questioned by the men of the place about his wife, he said, She is my sister; fearing to say, She is my wife; for, he said, the men of the place may put me to death on account of Rebekah; because she is very beautiful. 8 And when he had been there for some time, Abimelech, king of the Philistines, looking through a window, saw Isaac playing with Rebekah his wife. 9 And he said to Isaac, It is clear that she is your wife: why then did you say, She is my sister? And Isaac said, For fear that I might be put to death because of her. 10 Then Abimelech said, What have you done to us? one of the people might well have had connection with your wife, and the sin would have been ours. 11 And Abimelech gave orders to his people that anyone touching Isaac or his wife was to be put to death.

(Read Genesis 26:6-11)
There is nothing in Isaac's denial of his wife to be imitated, nor even excused. The temptation of Isaac is the same as that which overcame his father, and that in two instances. This rendered his conduct the greater sin. The falls of those who are gone before us are so many rocks on which others have split; and the recording of them is like placing buoys to save future mariners. This Abimelech was not the same that lived in Abraham's days, but both acted rightly. The sins of professors shame them before those that are not themselves religious.
