But it also says mountains erode and crumble. Mountains can be shaken and fall into the sea. God makes them quake, and they melt like wax. And it’s not just God who can move mountains. Anyone can do it if they believe they can. Hills can be removed or melt away, so no, they are not everlasting.
So some mountains are temporary, but maybe Mount Zion is different? Nope. All the mountains and hills will be brought low one day. Every mountain will be removed, so none of them can be found. The mountains will be overturned and the cliffs will crumble. God will crush them, level them, and lay them waste.
