There is nothing new in this
In a nutshell: The things are known. There is nothing new in what has been said and there is no point in prolonging the conversation.
("And the yokes and the men of falsehood and despair and the fire that they have made to Moab and the return of bread and the ancient things" - Proverbs 1:42, and also: "What are we here for? And the things are known, ancient" - Shaul Tchernikhovsky/ Shimcha Lau Douka)
