Isaiah 36:4 (KJV)

Now it came to pass in the fourteenth year of king Hezekiah, that Sennacherib king of Assyria came up against all the defenced cities of Judah, and took them.

And the king of Assyria sent Rabshakeh from Lachish to Jerusalem unto king Hezekiah with a great army. And he stood by the conduit of the upper pool in the highway of the fuller's field.

Then came forth unto him Eliakim, Hilkiah's son, which was over the house, and Shebna the scribe, and Joah, Asaph's son, the recorder.

I say, sayest thou, (but they are but vain words) I have counsel and strength for war: now on whom dost thou trust, that thou rebellest against me?

Lo, thou trustest in the staff of this broken reed, on Egypt; whereon if a man lean, it will go into his hand, and pierce it: so is Pharaoh king of Egypt to all that trust in him.

But if thou say to me, We trust in the LORD our God: is it not he, whose high places and whose altars Hezekiah hath taken away, and said to Judah and to Jerusalem, Ye shall worship before this altar?

Now therefore give pledges, I pray thee, to my master the king of Assyria, and I will give thee two thousand horses, if thou be able on thy part to set riders upon them.

How then wilt thou turn away the face of one captain of the least of my master's servants, and put thy trust on Egypt for chariots and for horsemen?
