Isaiah 39:3, 4

Then Isaiah the prophet went to King Hezekiah and asked, “What did those men say, and where did they come from?” “From a distant land,” Hezekiah replied. “They came to me from Babylon.”

The prophet asked, “What did they see in your palace?” “They saw everything in my palace,” Hezekiah said. “There is nothing among my treasures that I did not show them.”
