'Longer' in the Bible

"You are the salt of the earth. But if salt loses its flavor, how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people.

Jesus answered, "You unbelieving and perverse generation! How much longer must I be with you? How much longer must I endure you? Bring him here to me."

So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate."

No one was able to answer him a word, and from that day on no one dared to question him any longer.
