'Less' in the Bible

"How much less, then, can I answer him and choose my words to argue with him!

how much less man, who is abominable and corrupt, who drinks in evil like water!

how much less a mortal man, who is but a maggot -- a son of man, who is only a worm!"

How much less, then, when you say that you do not perceive him, that the case is before him and you are waiting for him!
