I wish I knew what those were.
I was feeling generous so I did the legwork for ya
All quotes are from the JW abomination of a "bible"
Ephesians 6:2,3, in reference to the command found in Exodus 20:12 and Deuteronomy 5:16.
“Honor your father and your mother” is the first command with a promise: “That it may go well with you and you may remain a long time on the earth.”
Matthew 19:17-19
He said to him: “Why do you ask me about what is good? One there is who is good. If, though, you want to enter into life, observe the commandments continually.” 18 He said to him: “Which ones?” Jesus said: “You must not murder, you must not commit adultery, you must not steal, you must not bear false witness, 19 honor your father and your mother, and you must love your neighbor as yourself.”
If you show that one to him, you can give it a little extra power by suggesting that it's significant that showing honor to one's parents was mentioned in the same breath as murder (this is a line of reasoning that JWs often use to increase the importance of relatively minor commands)
Romans 1:28-32
Just as they did not see fit to acknowledge God, God gave them over to a disapproved mental state, to do the things not fitting. And they were filled with all unrighteousness, wickedness, greed, and badness, being full of envy, murder, strife, deceit, and malice, being whisperers, backbiters, haters of God, insolent, haughty, boastful, schemers of what is harmful, disobedient to parents, without understanding, false to agreements, having no natural affection, and merciless. Although these know full well the righteous decree of God—that those practicing such things are deserving of death—they not only keep on doing them but also approve of those practicing them.
2 Timothy 3:1-7
But know this, that in the last days critical times hard to deal with will be here. For men will be lovers of themselves, lovers of money, boastful, haughty, blasphemers, disobedient to parents, unthankful, disloyal, having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, betrayers, headstrong, puffed up with pride, lovers of pleasures rather than lovers of God, having an appearance of godliness but proving false to its power; and from these turn away.
Again, in these verses having no natural affection is grouped with some other pretty bad stuff. Of course JWs are trained to recognize these verses as applying only to "worldly" people, so it might be a little difficult to make your point with them.
