Halakhah su Isaia 49:41

You should make a serious effort to pray with a congregation, as it is written; "As for me, may my prayer to You Hashem be at a favorable time."¹³Psalms 69:14. When is the time favorable? When the congregation prays together. It is [also] written: "Thus said Hashem; at a favorable time I have answered you."¹⁴Isaiah 49:8. The Holy One blessed is He never disdains the prayer of the multitude even though there are sinners in their midst, as it is written: "Behold, Hashem is mighty, (meaning He is the God of the multitude) yet He does not despise anyone."¹⁵Job 36:5. In Hebrew, kabbir also means many. It is [also] written: "He has redeemed my soul in peace from impending battle for the sake of the many that were with me."¹⁶Psalms 55:19.

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)."
