'High Places' in the Bible

They have gone up to Bayith, and to Dibon, to the high places, to weep. Moab wails over Nebo, and over Medeba. On all their heads is baldness. Every beard is cut off.

But if thou say to me, We trust in LORD our God. Is that not he whose high places and whose altars Hezekiah has taken away, and has said to Judah and to Jerusalem, Ye shall worship before this altar?

then thou shall delight thyself in LORD, and I will make thee to ride upon the high places of the earth, and I will feed thee with the heritage of Jacob thy father. For the mouth of LORD has spoken it.
