Isaiah 36:6 in the King James Version
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.
Context
5 I say that your counsel and strength for the war are only vain words. Now in whom do you trust, that you have rebelled against me?
6 Behold, you trust in the staff of this bruised reed, even in Egypt, which if a man leans on it, it will go into his hand and pierce it. So is Pharaoh king of Egypt to all who trust in him.
7 But if you tell me, ‘We trust in the LORD our God,’ isn’t that he whose high places and whose altars Hezekiah has taken away, and has said to Judah and to Jerusalem, ‘You shall worship before this altar’?”
