And Hezekiah received the letter from the hand of the messengers, and read it: and Hezekiah went up unto the house of the Lord, and spread it before the Lord. 15. And Hezekiah prayed unto the Lord, saying, 16. O Lord of hosts, God of Israel, that dwellest between the cherubims, Thou art the God, even Thou alone, of all the kingdoms of the earth: Thou hast made heaven and earth. 17. Incline Thine ear, O Lord, and hear; open Thine eyes, O Lord, and see: and hear all the words of Sennacherib, which hath sent to reproach the living God. 18. Of a truth, Lord, the kings of Assyria have laid waste all the nations, and their countries, 19. And have cast their gods into the fire: for they were no gods, but the work of men's hands, wood and stone: therefore they have destroyed them. 20. Now therefore, O Lord our God, save us from his hand, that all the kingdoms of the earth may know that Thou art the Lord, even Thou only. 21. Then Isaiah the son of Amoz sent unto Hezekiah, saying. Thus saith the Lord God of Israel, Whereas thou hast prayed to Me against Sennacherib king of Assyria. 33. Therefore thus saith the Lord concerning the king of Assyria, He shall not come into this city, nor shoot an arrow there, nor come before it with shields, nor cast a bank against it. 34. By the way that he came, by the same shall he return, and shall not come into this city, saith the Lord. 35. For I will defend this city to save it for mine own sake, and for my servant David's sake. 36. Then the angel of the Lord went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses. 37. So Sennacherib king of Asayria departed, and went and returned, and dwelt at Nineveh. 38. And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword; and they escaped into the land of Armenia: and Esarhaddon his son reigned in his stead.'--Isaiah 37:14-21, 33-38.
Is trust in Jehovah folly or wisdom? That was the question raised by Sennacherib's invasion. A glance at the preceding chapters will show how the high military official, the rabshakeh,' or chief of the officers, shaped all his insolent and yet skilful mixture of threats and promises so as to demonstrate the vanity of trust in Egypt or in Jehovah, or in any but the great king.' Isaiah had been labouring to lift his countrymen to the height of reliance on Jehovah alone, and now the crucial test of the truth of his contention had come. On the one hand were Sennacherib and his host, flushed with victory, and sure of crushing this puny kinglet Hezekiah and his obstinate little city, perched on its rock. On the other was nothing but a prophet's word. Where is the stronger force? And does political prudence dictate reliance on the Unseen or on the visible? The moment is the crisis of Isaiah's work, and this narrative has been placed, with true insight into its importance, at the close of the first half of this book.
To grasp the significance of the text the preceding events have to be remembered. Hezekiah's kingdom had been overrun, and tribute exacted from him. The rabshakeh had been sent from the main body of the Assyrian army, which was down at Lachish in the Philistine low country on the road to Egypt, in order to try to secure Jerusalem by promises and threats, since it was too important a post to leave in the rear, if Egypt was to be invaded. That attempt having failed, and the Egyptian forces being in motion, this new effort was made to induce Hezekiah to surrender.
The letter was sent, whether accompanied by any considerable armed force or no does not appear. At this point the narrative begins. It may be best studied as an illustration of the trial of faith, its refuge, its pleading, and its deliverance.
