2 Kings 20:13-15

13And Hezekiah received the envoys and showed them all that was in his treasure house—the silver, the gold, the spices, and the precious oil, as well as his armory—all that was found in his storehouses. There was nothing in his palace or in all his dominion that Hezekiah did not show them.

14Then the prophet Isaiah went to King Hezekiah and asked, “Where did those men come from, and what did they say to you?”

“They came from a distant land,” Hezekiah replied, “from Babylon.”

15“What have they seen in your palace?” Isaiah asked.

“They have seen everything in my palace,” answered Hezekiah. “There is nothing among my treasures that I did not show them.”
