'Holy Mountain' in the Bible

For in my holy mountain, in the mountain of the height of Israel, saith the Lord Jehovah, there shall all the house of Israel serve me, the whole of it, in the land; there will I accept them, and there will I require your heave-offerings and the first-fruits of your offerings, with all your holy things.

Thou wast the anointed covering cherub, and I had set thee so: thou wast upon the holy mountain of God; thou didst walk up and down in the midst of stones of fire.
