Charles Ellicott Commentary 2 Chronicles 25:16

"And it came to pass, as he talked with him, that [the king] said unto him, Have we made thee of the king`s counsel? forbear; why shouldest thou be smitten? Then the prophet forbare, and said, I know that God hath determined to destroy thee, because thou hast done this, and hast not hearkened unto my counsel." — 2 Chronicles 25:16 (ASV)

As he talked with him. — When he spoke to him.

Are you made of the king’s counsel? — Literally, A counsellor to the king have we appointed you?

Why should you be smitten? — Why should they smite you?

Has determined. — Has counselled. The prophet appropriates the king’s own word and implies his participation in Divine, if not in royal, counsels.

Because. — The conduct of Amaziah was proof that God had “counselled to destroy him.”

You have done this. — Spurned my warning. Others say: because you have adopted the Edomite gods.

To my counsel. — Again repeating the king’s expression.
