Read Isaiah 36:6 Using Other Translations
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.
Behold, you are trusting in Egypt, that broken reed of a staff, which will pierce the hand of any man who leans on it. Such is Pharaoh king of Egypt to all who trust in him.
On Egypt? If you lean on Egypt, it will be like a reed that splinters beneath your weight and pierces your hand. Pharaoh, the king of Egypt, is completely unreliable!
