Of course, we know the WTS points to many "right" reasons to lie to non-members, even to Jesus. So if Jesus can lie, they can lie, in their minds. Did Jesus lie to his disciples?
*** it-2 p. 245 Lie ***
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. Jesus Christ counseled: “Do not give what is holy to dogs, neither throw your pearls before swine, that they may never trample them under their feet and turn around and rip you open.” (Mt 7:6) That is why Jesus on certain occasions refrained from giving full information or direct answers to certain questions when doing so could have brought unnecessary harm. (Mt 15:1-6; 21:23-27; Joh 7:3-10) Evidently the course of Abraham, Isaac, Rahab, and Elisha in misdirecting or in withholding full facts from nonworshipers of Jehovah must be viewed in the same light.—Ge 12:10-19; chap 20; 26:1-10; Jos 2:1-6; Jas 2:25; 2Ki 6:11-23.

For example, individuals with wicked intent may have no right to know certain things. Christians understand that they are living in a hostile world. Thus, Jesus advised his disciples to be “cautious as serpents” while remaining “innocent as doves.” (Matthew 10:16; John 15:19) Jesus did not always disclose the full truth, especially when revealing all the facts could have brought unnecessary harm to himself or his disciples. Still, even at such times, he did not lie. Instead, he chose either to say nothing or to divert the conversation in another direction.—Matthew 15:1-6; 21:23-27; John 7:3-10.
Faithful men and women mentioned in the Bible, such as Abraham, Isaac, Rahab, and David, were likewise shrewd and cautious when dealing with potential enemies. (Genesis 20:11-13; 26:9; Joshua 2:1-6; 1 Samuel 21:10-14) The Bible classifies such men and women as faithful worshipers whose lives were characterized by obedience. That makes them worthy of imitation.—Romans 15:4; Hebrews 11:8-10, 20, 31, 32-39.
