Halakhah do Izajasza 49:3

And the laws of this commandment are included in the commandment, as the general principle of everything is that a man behave with his fellow in the way that a man behaves [with] himself - to guard his money and to distance all injury from him. And if he recounts things about him, he recounts them for praise, and he relate to his honor; and he does not become honored through his disgrace - and as they, may their memory be blessed, said (Talmud Yerushalmi Chagigah 2:1), "One who is honored by the disgrace of his fellow has no share in the world to come, but one who treats his fellow with love, peace and neighborliness, seeks their benefit and is happy about their good, the verse states about him, 'Israel, about you will I be glorified' (Isaiah 49:3)."
