And Hezekiah had exceeding much riches
 Increased by the spoil of the Assyrian camp, and the presents sent him after that by neighbouring nations, ( 2 Chronicles 32:21 2 Chronicles 32:23 ) 
 and honour;
 both from his subjects, and the nations around him: 
 and he made himself treasuries for silver, and for gold, and for
 precious stones, and for spices, and for shields, and for all manner
 of pleasant jewels:
 which were houses both for rich and curious things, and for armour, he showed to the ambassadors of Babylon, (See Gill on Isaiah 39:2).
