48:7 “Moab, you trust in the things you do and in your riches.
So you too will be conquered.
Your god Chemosh 1 will go into exile 2
along with his priests and his officials.
51:16 When his voice thunders, the waters in the heavens roar.
He makes the clouds rise from the far-off horizons.
He makes the lightning flash out in the midst of the rain.
He unleashes the wind from the places where he stores it.
1 sn Chemosh was the national god of Moab (see also Numb 21:29). Child sacrifice appears to have been a part of his worship (2 Kgs 3:27). Solomon built a high place in Jerusalem for him (1 Kgs 11:7), and he appears to have been worshiped in Israel until Josiah tore that high place down (2 Kgs 23:13).
2 sn The practice of carrying off the gods of captive nations has already been mentioned in the study note on 43:12. See also Isa 46:1-2 noted there.
