'Mountain of God' in the Bible

Thou wast the anointed cherub that covereth: and I set thee,'so that thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.

By the abundance of thy traffic they filled the midst of thee with violence, and thou hast sinned: therefore have I cast thee as profane out of the mountain of God; and I have destroyed thee, O covering cherub, from the midst of the stones of fire.
