I found the "Flock" Book 1981 version.
On page 150 under the subject "Guidelines for Proper Christian Administration of Justice with Mercy" (started on page 145) #(5) Self-Defence says: "A Christian woman threatened with rape should resist by screaming and physically resisting (Deut.22:23-2, 1 Cor 6:18) Other details are given in W68 6/1 pp345-350: Awake73 4/22 pp16.17)"
The WT CD-ROM does not include 1968 WT volumes but here is what the Awake of 1973 says along with the supporting scriptures:
*** g73 4/22 17 Protect Yourself from Crime ***
"Yes, scream! This is wise advice and stands in contrast with the growing number who encourage women passively to allow themselves to be raped, or to bargain with the rapist for their lives. But, if a woman allows a man to rape her, how does she know that he will not kill her afterward?
Interestingly, in Gods law to Israel the primary distinction between rape and consent was whether a woman screamed for help. In modern cities onlookers have been known to watch as a woman was raped, assuming she was consenting to an act of exhibitionism since she did not scream or otherwise resist her attacker.Read the Biblical law at Deuteronomy 22:23-29"
(Deuteronomy 22:23-29) "In case there happened to be a virgin girl engaged to a man, and a man actually found her in the city and lay down with her, 24
YOU must also bring them both out to the gate of that city and pelt them with stones, and they must die, the girl for the reason that she did not scream in the city, and the man for the reason that he humiliated the wife of his fellowman. So you must clear away what is evil from your midst. 25
"If, however, it is in the field that the man found the girl who was engaged, and the man grabbed hold of her and lay down with her, the man who lay down with her must also die by himself, 26
and to the girl you must do nothing. The girl has no sin deserving of death, because just as when a man rises up against his fellowman and indeed murders him, even a soul, so it is with this case. 27
For it was in the field that he found her. The girl who was engaged screamed, but there was no one to rescue her. 28
"In case a man finds a girl, a virgin who has not been engaged, and he actually seizes her and lies down with her, and they have been found out, 29
the man who lay down with her must also give the girls father fifty silver shekels, and she will become his wife due to the fact that he humiliated her. He will not be allowed to divorce her all his days.
(1 Corinthians 6:18) Flee from fornication. Every other sin that a man may commit is outside his body, but he that practices fornication is sinning against his own body.
Its quite plain that at this time the WTS equated not screaming when being raped with fornication worthy of being stoned to death in Biblical times but the equivalent punishment in modern times would be df'ing.
Also, this scripture was handwritten in the margin of my copy, as an additional reference:
(Ecclesiastes 9:18) Wisdom is better than implements for fighting, and merely one sinner can destroy much good.
I'm not quite sure why though!
Hope this helps your search Nathan.
