Isaiah 36:4

The testimony of Rabshakeh is that he relies on the Lord, who has captured all the cities of Judah and said to the people: Do not be afraid and do not be dismayed before the king of Assyria and all the multitude that is with him, for there are more with us than with him. With him is an arm of flesh; with us is the Lord our God, our helper, who fights for us. And the people were strengthened by the words of Hezekiah, king of Judah.

Rabshekah addressed them as follows: "Tell Hezekiah: This is what the great king, the king of Assyria, says..." and so on, as recorded in the history. In this, we can see the arrogance of Rabshekah, who, in a manner contrary to true strength, imitates the custom of the prophets. While they usually begin their pronouncements with "This is what the Lord says," he now says, "This is what the great king, the king of Assyria, says."

(Chapter 36—Verse 1 and following) And it came to pass in the fourteenth year of King Hezekiah, Sennacherib king of Assyria came up against all the fortified cities of Judah and captured them.

And Eliakim the son of Hilkiah, who was over the household, and Shebna the secretary, and Joah the son of Asaph, the recorder, came out to him. And Rabshakeh said to them, "Say to Hezekiah, 'Thus says the great king, the king of Assyria: On what do you rest this trust of yours?' By what plan and courage do you prepare to rebel? On whom do you have confidence, because you have turned away from me? Look, you trust in this broken reed staff, in Egypt: if a man leans on it, it will enter into his hand and pierce it. So is Pharaoh, the king of Egypt, to all who trust in him. But if you say to me, 'We trust in the LORD our God,' is it not he whose heights and altars Hezekiah has taken away, and said to Judah and Jerusalem, 'You shall worship before this altar'? And now make a deal with my master the king of Assyria, and I will give you two thousand horses, and you will not be able to provide riders for them. And how will you withstand the face of one judge from my lord's servants? And if you rely on Egypt: and on chariots, and on horsemen: and now, did I ascend to this land without the Lord, to destroy it? The Lord said to me: Go up on this land and destroy it. The history is clear and does not require interpretation: and this same thing is reported more fully in the volumes of Kings and Chronicles. In the third year of Hosea the son of Elah, king of Israel, Hezekiah the son of Ahaz king of Judah began to reign. […]

And Rabsaces said to them. Here the discussion of the messengers is set out. And concerning this, he sets out two things: first, the preamble of Rabsaces to the Jewish messengers; second, to the others, where it says, then Rabsaces stood (Isa 36:13). Concerning the …
