Albert Barnes Commentary 2 Chronicles 34:32

"And he caused all that were found in Jerusalem and Benjamin to stand [to it]. And the inhabitants of Jerusalem did according to the covenant of God, the God of their fathers." — 2 Chronicles 34:32 (ASV)

And Benjamin - It is scarcely possible that the text here can be sound. “Benjamin” is never put in contrast with “Jerusalem,” but always with Judah. The reading may be corrected from the parallel passage 2 Kings 23:3: And he caused all those that were present in Jerusalem to stand to the covenant.
