'High' in the Bible

Though I sent destruction on the Amorite before them, who was tall as the cedar and strong as the oak-tree, cutting off his fruit from on high and his roots from under the earth.

For see, he who gave form to the mountains and made the wind, giving knowledge of his purpose to man, who makes the morning dark, and is walking on the high places of the earth: the Lord, the God of armies, is his name.

And the high places of Isaac will be unpeopled, and the holy places of Israel will be made waste; and I will come up against the family of Jeroboam with the sword.
