'Mountain' in the Bible

And it will be [that] at the end of those days, the mountain of Yahweh will be established as the highest of the mountains, and it will be lifted up above the hills, and people will stream to it.

And many nations will come and say, "Come! Let us go up to the mountain of Yahweh, and to the {temple} of the God of Jacob, that he may teach us his ways, and that we may walk in his paths," for the law will go out from Zion, and the word of Yahweh from Jerusalem.

[On] that day he will come to you from Assyria and the cities of Egypt, and from Egypt to the River, and from sea to sea and mountain to mountain.
