'High places' in the Bible

Dibon went up to its templeto weep at its high places.Moab wails on Nebo and at Medeba.Every head is shaved;every beard is cut off.

Suppose you say to me, ‘We trust in the Lord our God.’ Isn’t He the One whose high places and altars Hezekiah has removed, saying to Judah and Jerusalem, ‘You are to worship at this altar’?
