'Really' in the Bible

"Stop trusting in human beings, whose life breath is in their nostrils, for what are they really worth?"

"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?

One other thing: have I really marched against this country to destroy it apart from the LORD's direction? The LORD himself ordered me, "March against this country to destroy it.'"

Don't let Hezekiah persuade you to rely on the LORD when he says, "The LORD will really deliver us!" and "This city will never be handed over to the king of Assyria!"
