Isa 36:6-9

6 See, you are relying on Egypt, that broken reed of a staff, which will pierce the hand of anyone who leans on it. Such is Pharaoh king of Egypt to all who rely on him. 7 But if you say to me, ‘We rely on the Lord our God,’ is it not he whose high places and altars Hezekiah has removed, saying to Judah and to Jerusalem, ‘You shall worship before this altar’? 8 Come now, make a wager with my master the king of Assyria: I will give you two thousand horses, if you are able on your part to set riders on them. 9 How then can you repulse a single captain among the least of my master’s servants, when you rely on Egypt for chariots and for horsemen?
