Hebrews 12:22

But ye are come unto mount Sion, &c.— There seems to be throughout this whole period a reference to the manifestation which God made of himself upon mount Sion, as being milder than that upon mount Sinai, and the heavenly society with which Christians are incorporated, is considered as resembling the former, (that is, mount Sion,) in those circumstances in which it was more amiable than the latter. Sion was the city of God: in the temple which stood there, cherubims were the ornaments of the walls, both in the holy and most holy place, to signify the presence of those myriads of angels, who attended at the giving of the law, and are present in the true heavens. There (in the city of Sion) was a general assembly and congregation of the priests, who were substituted instead of the first-born: there was God, as the supreme Judge of controversies, giving forth his oracles; the high-priest was the mediator between God and Israel; and the blood of sprinkling was daily used.
