What is the difference between "Bamos" and "Chamanim"?
Rashi: 'Bamos' are towers and castles, and 'Chamanim', a kind of idol that they placed on their rooftops facing the sun. 1
Rashbam, Targum Onkelos and Targum Yonasan: 'Bamos' refers to the altars that they built (to sacrifice to their gods and 'Chamanim', to diviners and sorcerers - Targum Yonasan).
Chizkuni: It is based on the word 'Chamah', and the 'Nun' is extra. Presumably, it was a form of sun-god.
