Isaiah 36:6 (KJV)

And Rabshakeh said unto them, Say ye now to Hezekiah, Thus saith the great king, the king of Assyria, What confidence is this wherein thou trustest?

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.
