Halakhah zu Tehillim 55:19

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.
