'Mountains' in the Bible

Melted have been the mountains under Him, And the valleys do rend themselves, As wax from the presence of fire, As waters cast down by a slope.

Hear, I pray you, that which Jehovah is saying: 'Rise -- strive thou with the mountains, And cause thou the hills to hear thy voice.'

Hear, O mountains, the strife of Jehovah, Ye strong ones -- foundations of earth! For a strife is to Jehovah, with His people, And with Israel He doth reason.
