'High Mountain' in the Bible

For on my holy mountain, on Israel's high mountains," declares the Lord GOD, "the whole of Israel's house all of it will serve me there in the land. I'll accept them there. And there I'll demand your offerings, the first fruits of your portions of all your sacred things.

God brought me in a series of visions to the land of Israel and placed me on top of a very high mountain, where to the south there was something that looked like the outline of a city.
