Hebrews 12:22

But ye are come to mount Zion, and unto the city of the living God, the heavenly Jerusalem, and to innumerable hosts of angels.

For notes on "angels" and the "city of the living God," see under those titles following Hebrews 1:14 and Hebrews 11:10.

At this place, the author turns to a presentation of the glories of the central authority in Christianity, a contrast being at once evident in the two mountains. Sinai was an alien mountain in a foreign land; and Zion was the poetic name for Jerusalem, the name of the eminence upon which the city was built, and which enshrined the deepest emotional affection of the whole Hebrew nation. The prophets had extolled the word of the Lord as going forth from Mount Zion (Isaiah 2:3); it was toward Mount Zion that the captive Daniel had prayed in Babylon; and even Jesus Christ referred to it as the "city of the great King" (Matthew 5:35).
