13 And Hezeki'ah welcomed them, and he showed them all his treasure house, the silver, the gold, the spices, the precious oil, his armory, all that was found in his storehouses; there was nothing in his house or in all his realm that Hezeki'ah did not show them. 14 Then Isaiah the prophet came to King Hezeki'ah, and said to him, "What did these men say? And whence did they come to you?" And Hezeki'ah said, "They have come from a far country, from Babylon." 15 He said, "What have they seen in your house?" And Hezeki'ah answered, "They have seen all that is in my house; there is nothing in my storehouses that I did not show them."

Commentary on 2 Kings 20:12-21
(Read 2 Kings 20:12-21)
The king of Babylon was at this time independent of the king of Assyria, though shortly after subdued by him. Hezekiah showed his treasures and armour, and other proofs of his wealth and power. This was the effect of pride and ostentation, and departing from simple reliance on God. He also seems to have missed the opportunity of speaking to the Chaldeans, about Him who had wrought the miracles which excited their attention, and of pointing out to them the absurdity and evil of idolatry. What is more common than to show our friends our houses and possessions? But if we do this in the pride of ours hearts, to gain applause from men, not giving praise to God, it becomes sin in us, as it did in Hezekiah. We may expect vexation from every object with which we are unduly pleased. Isaiah, who had often been Hezekiah's comforter, is now is reprover. The blessed Spirit is both, John 16:7,8. Ministers must be both, as there is occasion. Hezekiah allowed the justice of the sentence, and God's goodness in the respite. Yet the prospect respecting his family and nation must have given him many painful feelings. Hezekiah was indeed humbled for the pride of his heart. And blessed are the dead who die in the Lord; for they rest from their labours, and their works do follow them.
