didn't moses lie to the egyptians about sarah. he said it was his sister instead of his wife to protect her. i think the WTS uses this example to justify lieing to protect themselves and promote "theocratic warefare".
Genesis Chapter 1210 Now a famine arose in the land and A´bram made his way down toward Egypt to reside there as an alien, because the famine was severe in the land. 11 And it came about that as soon as he got near to entering Egypt, then he said to Sar´ai his wife: ?Please, now! I well know you are a woman beautiful in appearance. 12 So it is bound to happen that the Egyptians will see you and will say, ?This is his wife.? And they will certainly kill me, but you they will preserve alive. 13 Please say you are my sister, in order that it may go well with me on your account, and my soul will be certain to live due to you.?
14 So it happened that, as soon as A´bram entered Egypt, the Egyptians got to see the woman, that she was very beautiful. 15 And the princes of Phar´aoh also got to see her and they began praising her to Phar´aoh, so that the woman was taken to the house of Phar´aoh. 16 And he treated A´bram well on her account, and he came to have sheep and cattle and asses and menservants and maidservants and she-asses and camels. 17 Then Jehovah touched Phar´aoh and his household with great plagues because of Sar´ai, A´bram?s wife. 18 With that Phar´aoh called A´bram and said: ?What is this you have done to me? Why did you not tell me that she was your wife? 19 Why did you say, ?She is my sister,? so that I was about to take her as my wife? And now here is your wife. Take her and go!? 20 And Phar´aoh issued commands to men concerning him, and they went escorting him and his wife and all that he had.
