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, Joh 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.

12-19. Berodach-baladan—(Isa 39:1), the first king of Babylon mentioned in sacred history; formerly its rulers were viceroys of the Assyrian monarchs. This individual threw off the yoke, and asserting his independence, made with varying success, a long and obstinate resistance [Rawlinson, Outlines]. The message of congratulation to Hezekiah, was, in all likelihood, accompanied with proposals for a defensive alliance against their common Assyrian enemy. The king of Judah, flattered with this honor, showed the ambassadors all his treasures, his armory and warlike stores; and his motive for this was evidently that the Babylonian deputies might be the more induced to prize his friendship.
