This scripture is often used at the Kingdom Hall: Psalms 133:1 "Look! How good and how pleasant it is, For brothers to dwell together in unity! One of my favorite scripture! Hopes you like it too. :)
Revelation 18:4,5 " And I heard another voice out of heaven say ; Get out of her my people, If you do not want to share with her in her sins and if you do not want to receive part of her plagues,for her sins have massed together clear up to haven,and God has called her acts of injustice to mind."
