'Less' in the Bible

“But will God actually dwell with mankind on the earth? Behold, heaven and the highest heaven cannot contain You; how much less this house which I have built!

So now, do not let Hezekiah deceive or mislead you like this, and do not believe him, for no god of any nation or kingdom has been able to rescue his people from my hand or the hand of my fathers. How much less will your God rescue you from my hand!’”
