'High places' in the Bible

He made him ride on the high places of the earth, And he ate the produce of the field; And he made him suck honey out of the crag, And oil out of the flinty rock;

Happy art thou, Israel! Who is like unto thee, a people saved by Jehovah, The shield of thy help, And the sword of thine excellency? And thine enemies shall come cringing to thee; And thou shalt tread upon their high places.
