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. The staff of this broken reed - A weakened, faithless ally.
On Egypt - The Bodl. MS. adds מלך melech, the king of Egypt; and so perhaps the Chaldee might read.
It will go into his hand, and pierce it - Will take subsidy after subsidy, and do nothing for it.
