'Mountains' in the Bible

And I turn back, and lift up mine eyes, and look, and lo, four chariots are coming forth from between two of the mountains, and the mountains are mountains of brass.

And ye have fled to the valley of My mountains, For join doth the valley of the mountains to Azal, And ye have fled as ye fled before the shaking, In the days of Uzziah king of Judah, And come in hath Jehovah my God, All holy ones are with Thee.
