It must be that they were nearer to perfection in those days!
It can clearly be established that Abraham was ten years older than Sarah (Gen 17:17)
At the age of 75, when Sarah was 65, they set out to visit Egypt due to a famine.
(Gen 12:4,5)
Now heres the interesting bit as they approached Egypt Abram asked Sarah to lie to save his butt. In effect, Sarah was so beautiful (at 65!) that Abram knew that the Egyptians would kill him to get hold of her. (Gen 12: 11,12,13)
It worked. Thinking she was Abrams sister, Pharaoh fell for her and wanted to marry her. But then the truth was revealed when Jehovah started to mess the Egyptians up (why?). So Pharaoh told Abram and Sarai to leave.
Call me cynical, but I find it hard to believe that a Pharaoh, with access to all the young tottie in his kingdom, would fall for a 65-year-old woman who had spent most of her life in the harsh desert.
And also worthy of note, Jehovah did not condemn and even supported the lie. Perhaps this is the biblical precedent the Society use to support their bare faced lies?
