'Less' in the Bible

"But will God indeed dwell with men on the earth? Behold, heaven and the heaven of heavens can't contain you; how much less this house which I have built!

Now therefore don't let Hezekiah deceive you, nor persuade you in this way, neither believe him; for no god of any nation or kingdom was able to deliver his people out of my hand, and out of the hand of my fathers. How much less will your God deliver you out of my hand?"
