Hebrews 12:22–24
Instead, you have come to Mount Zion, to the city of the living God, the heavenly Jerusalem. You have come to myriads of angels / in joyful assembly, to the congregation of the firstborn, enrolled in heaven. You have come to God the Judge of all, to the spirits of the righteous made perfect, / to Jesus the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
