Charles Ellicott Commentary 2 Chronicles 30:7

"And be not ye like your fathers, and like your brethren, who trespassed against Jehovah, the God of their fathers, so that he gave them up to desolation, as ye see." — 2 Chronicles 30:7 (ASV)

And do not be like your fathers. —From the days of Jeroboam onward.

And like your brothers. —Of Naphtali and the Trans-Jordan, whom Tiglath-pileser took captive.

Trespassed. — Were unfaithful to Jehovah.

Who therefore gave them up to desolation. — And He made them an astonishment (2 Chronicles 29:8).
