'Relying' in the Bible

Then the Rabshakeh said to them, “Tell Hezekiah this is what the great king, the king of Assyria, says: ‘What are you relying on?

You think mere words are strategy and strength for war. What are you now relying on so that you have rebelled against me?

""Now who are you relying on, that you have rebelled against me? Look, you're trusting on Egypt to lean on like a staff, but it's a crushed reed, and if you lean on it, it will collapse and pierce your hand. Pharaoh, king of Egypt, is just like that to everyone who relies on him!
