Genesis 26:6

Rebekah preserved from dishonor in Gerar. Gerar was probably a commercial town trading with Egypt, and therefore Isaac's needs during the famine are here supplied. "The men of the place" were struck with the appearance of Rebekah, "because she was fair." Isaac, in answer to their inquiries, pretends that she is his sister, feeling that his life was in peril, if she was known to be his wife. Rebekah was at this time not less than thirty-five years married, and had two sons upwards of fifteen years old. She was still however in the prime of life, and her sons were probably engaged in pastoral and other field pursuits. From the compact between Abraham and Sarah Genesis 20:13, and from this case of Isaac about eighty years after, it appears that this was a ready pretence with married people among strangers in those times of social insecurity.
