'Less' in the Bible

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

Now therefore, do not let Hezekiah deceive you or mislead you like this, and do not believe him, for no god of any nation or kingdom was able to deliver his people from my hand or from the hand of my fathers. How much less will your God deliver you from my hand?’”
