Isiah 36: 4-6
4 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?
5 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?
6 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.
Psalm 118 8,9
8 It is better to trust in the LORD than to put confidence in man.
9 It is better to trust in the LORD than to put confidence in princes.
