Charles Ellicott Commentary 2 Chronicles 25:15

"Wherefore the anger of Jehovah was kindled against Amaziah, and he sent unto him a prophet, who said unto him, Why hast thou sought after the gods of the people, which have not delivered their own people out of thy hand?" — 2 Chronicles 25:15 (ASV)

Could not deliver. — Did not deliver. (Compare to the boast of Sennacherib concerning the gods who had failed before him: 2 Kings 18:33–35.)

The king’s object may have been to win their favor, and so retain his hold on what was regarded as their own particular territory.

One of these gods might be Hadad (Compare to 1 Chronicles 1:46; 1 Chronicles 1:50; 2 Kings 5:18; 2 Kings 6:24).

Another might have been Kôsh. (Compare to the Edomite royal names Qa-us-ma-la-ka, i.e., Kosmalak, “Kosh is king,” and Qa-us-gab-ri, i.e., Kosgabri, “Kosh is my warrior”—names which are like the Hebrew Elimelech and Gabriel respectively.) The Hebrew proper name, Kish, may be the same as Kôsh.

Lastly, the name of a king of Edom mentioned by Sennacherib, Mâlik-rammu, i.e., “Moloch is exalted,” indicates that Moloch also was worshipped in Edom.
