'Depending' in the Bible

"Tell Hezekiah, king of Judah, "This is what the mighty king, the king of Assyria, has to say: What is this "guarantee" that makes you yourself rely on it? Do you really think that guarantees alone can withstand strategy and military strength? On whom are you now depending, that you're rebelling against me?

But if you all say to me, "We are depending on the LORD our God" - isn't he the one whose high places and altars Hezekiah removed, while he kept on telling Judah and Jerusalem, "You are to worship in front of this altar in Jerusalem'?

How, then, can you repulse even one officer from the least of my master's officials, when you are depending for yourselves on Egypt for chariots and horsemen?
