Charles Ellicott Commentary 2 Chronicles 12:9

"So Shishak king of Egypt came up against Jerusalem, and took away the treasures of the house of Jehovah, and the treasures of the king`s house: he took all away: he took away also the shields of gold which Solomon had made." — 2 Chronicles 12:9 (ASV)

So Shishak king of Egypt came up against Jerusalem. —The narrative is resumed after the parenthesis relating to Shemaiah by repeating the statement of 2 Chronicles 12:2.

And took away the treasures of the house of the Lord. —See 1 Kings 14:26, with which the rest of this verse is identical.
