Found this on the net......very interesting seeing as it comes from the JW's own literature.
1960 "the Scriptures justify the 'war strategy' of hiding true facts from the enemy." (Watchtower May 15, 1960, page 295)
1960 "As a soldier of Christ he is in theocratic warfare and he must exercise caution when dealing with God's foes. Thus the Scriptures show that for the purpose of protecting the interests of God's cause, it is proper to hide the truth from God's enemies." (Watchtower; 6/1/1960; p. 352)
"While malicious lying is definitely condemned in the Bible, this does not mean that a person is under obligation to divulge truthful information to people who are not entitled to it. … Evidently the course of Abraham, Isaac, Rahab, and Elisha in misdirecting or in withholding full facts from non-worshipers of Jehovah must be viewed in the same light.-Ge 12:10-19; chap 20 [Abraham lying to Pharoah and Abimelech]; 26:1-10 [Issac lying to Abimelech]; Jos 2:1-6; Jas 2:25 [Rahab lying to king of Jericho]". (Insight on the Scriptures, it-2 245, Note: bracketed text [ ] added. It would be interesting to see how Jw's view Noah's example of getting drunk and Lot's example of incest.)
1993 "Rahab--Declared Righteous by Works of Faith, What about Rahab's misleading words to pursuers of the spies? God approved of her course. (Compare Romans 14:4) She took a risk in order to protect his servants, giving evidence of her faith. While malicious lying is wrong in Jehovah's eyes, a person is not obligated to divulge truthful information to people who are not entitled to it. Even Jesus Christ did not give full details or direct answers when doing so could have brought unnecessary harm. (Matthew 7:6; 15:1-6; 21:23-27; John 7:3-10) Evidently, Rahab's course of misdirecting the enemy officers must be view in that light." (Watchtower 114:24, Dec. 15, 1993, p. 25)
