I had a family relative use this scripture found here to justify shunning. The scripture reads as followed
If, now, your right eye is making you stumble, tear it out and throw it away from you.+For it is better for you to lose one of your members than for your whole body to be pitched into Ge·henʹna.*+ 30 Also, if your right hand is making you stumble, cut it off and throw it away from you.+For it is better for you to lose one of your members than for your whole body to land in Ge·henʹna.
Now my personal opinion is that at first glance it looks like it is something that Jesus said that justifies shunning but if you read back to a couple verses before 29 and 30 you will find that Jesus is speaking of adultery and the scriptures read:
You heard that it was said: ‘You must not commit adultery.’+ 28 But I say to you that everyone who keeps on looking at a woman+ so as to have a passion for her has already committed adultery with her in his heart.
Correct me if I’m wrong but using this in the context of shunning is incorrect. I interpret the scripture as being more anti masturbation as opposed to being pro shunning to having your right eye and right hand removed if you look at woman with lust.
I think it’s one of those scriptures that are misapplied by Witnesses to be pro shunning when taken out of context. It’s annoying that they do that
