Talmud do Izajasza 66:20

Rebbi Phineas in the name of Rebbi Hoshaiah: He who prays in the synagogue is as if he had sacrificed a pure flour offering. What is the reason? (Is. 66:20) “As the children of Israel bring flour offering in a pure vessel in the Eternal’s House.³⁶Since the actual flour offering was brought by the Cohanim, the prophet speaks here of a symbolic act.” Rebbi Jeremiah in the name of Rebbi Abbahu: (Is. 55:6) “Seek the Eternal where He is to be found”. Where is He to be found? In synagogues and houses of study. “Call on Him when He is close.” Where is He close? In synagogues and houses of study. Rebbi Isaac ben Rebbi Eleazar said, not only that but their God stands over them. What is the reason? (Ps. 81:1) “God stands in the assembly of the mighty; from the inside God will judge.”
