Charles Ellicott Commentary 2 Chronicles 12:11

"And it was so, that, as oft as the king entered into the house of Jehovah, the guard came and bare them, and brought them back into the guard-chamber." — 2 Chronicles 12:11 (ASV)

And when. — And as often as.

The guard came and fetched ...— The runners came and bore them; and they (after the royal procession) restored them to the guard room of the runners. (See 1 Kings 14:28, which reads, the runners used to bear them.)

Solomon’s golden shields had been kept in the house of the forest of Lebanon (2 Chronicles 9:16).
