“And it was when King Hezekiah heard, that he rent his garments, and covered himself with sackcloth, and came to the house of the Lord (Isaiah 37:1).” It looks like the messengers have conveyed their instructions. The king then sends his own messengers to Isaiah. They tell him about the tragedy of the day and the problems coming from Assyria. But luckily, Isaiah is able to reassure them. “And Isaiah said to them, ‘So shall you say to your master, ‘So has the Lord said, ‘Have no fear of the words you have heard, that the servants of the king of Assyria have blasphemed Me (Isaiah 37:6).'” But Assyria keeps threatening Hezekiah and the kingdom, so Hezekiah goes to pray to God.
“And now, O Lord our God, deliver us from his hand, so that all the kingdoms of the earth may know that You are the Lord alone (Isaiah 37:20).” God does listen to this supplication, but not everything is going to be easy. Israel will be largely destroyed, but there will be survivors, and the remnant of Israel will reproduce and flourish once again. Assyria won’t be able to hurt Israel though, because God will protect Jerusalem. God ends up sending an angel to Assyria, and the angel destroys 185,000 in the Assyrian camp. It’s a tragic ending for the people, but a strong showing for God’s might.
