12 Soon after this, Merodach-baladan son of Baladan, king of Babylon, sent Hezekiah his best wishes and a gift, for he had heard that Hezekiah had been very sick. 13 Hezekiah received the Babylonian envoys and showed them everything in his treasure-houses-the silver, the gold, the spices, and the aromatic oils. He also took them to see his armory and showed them everything in his royal treasuries! There was nothing in his palace or kingdom that Hezekiah did not show them. 14 Then Isaiah the prophet went to King Hezekiah and asked him, "What did those men want? Where were they from?" Hezekiah replied, "They came from the distant land of Babylon." 15 "What did they see in your palace?" Isaiah asked. "They saw everything," Hezekiah replied. "I showed them everything I own-all my royal treasuries." 16 Then Isaiah said to Hezekiah, "Listen to this message from the Lord : 17 The time is coming when everything in your palace-all the treasures stored up by your ancestors until now-will be carried off to Babylon. Nothing will be left, says the Lord . 18 Some of your very own sons will be taken away into exile. They will become eunuchs who will serve in the palace of Babylon's king." 19 Then Hezekiah said to Isaiah, "This message you have given me from the Lord is good." For the king was thinking, "At least there will be peace and security during my lifetime."
20 The rest of the events in Hezekiah's reign, including the extent of his power and how he built a pool and dug a tunnel to bring water into the city, are recorded in 21 Hezekiah died, and his son Manasseh became the next king.

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.
