John Gill Commentary 2 Kings 11:10

"And the priest delivered to the captains over hundreds the spears and shields that had been king David`s, which were in the house of Jehovah." — 2 Kings 11:10 (ASV)

And to the captains over hundreds did the priest give King David's spears and shields, that were in the temple of the Lord . Such as he had taken in war from his enemies, and had dedicated for the service of the temple, to defend it on occasion, and laid up there; those the priests gave to the captains, to arm their men with, who came unarmed, and so unsuspected, and in this way might be armed without being seen and known.
