Albert Barnes Commentary 2 Chronicles 24:6

"And the king called for Jehoiada the chief, and said unto him, Why hast thou not required of the Levites to bring in out of Judah and out of Jerusalem the tax of Moses the servant of Jehovah, and of the assembly of Israel, for the tent of the testimony?" — 2 Chronicles 24:6 (ASV)

It appears from 2 Kings 12:4 that Joash had also assigned two other payments to the restoration fund.
