2 Kings 19-20
Chapter 19: Hezekiah Seeks Counsel from Isaiah
Hezekiah rents his clothes and covers himself with sackcloth and went into the house of the Lord. Hezekiah sends Eliakim and Shebna also covered in sackcloth to see Isaiah the son of Amoz.
Isaiah receives word from the Lord and tells the messengers to return to Hezekiah saying; “…Be not afraid of the words which thou hast heard, with which the servants of the king of Assyria have blasphemed me. Behold I will send a blast upon him, and he shall hear a rumour, and shall return to his own land; and I will cause him to fall by the sword in his own land.” (2 Kings 19:6-7)
But the king of Assyria (after Hezekiah had heard the above words), tells Hezekiah to not put trust in his God, because the other nations that have fallen into his hands have also put their trust in their gods and they fell under his rule.
But Hezekiah prays to the Lord asking him for deliverance to show the rest of the people roundabout that the Lord God is the ONLY God. Isaiah hears from the Lord and sends message to Hezekiah saying that his prayers would be answered. In the middle of the night an angel comes and slays 185,000 Assyrians while they slept in their camps and Sennacherib the King of Assyria flees only to be killed by his own sons (Adrammelech and Sharezer). Esarhaddon his other son reigned in his place.
Chapter 20: Hezekiah Pleads with the Lord
Hezekiah is on his death bed and is visited by Isaiah who tells him to set his house in order, because the Lord had told him that he will not live, but surely die. So Hezekiah pleads with the Lord to heal him and permit him more time. So the Lord tells Isaiah to deliver a message to Hezekiah that his prayers had been heard and that he would receive fifteen more years.
Isaiah prophesies about the Babylonian captivity of Judah and Hezekiah dies and is buried. His son Manasseh reigns in his stead.
