'Surely' in the Bible

Then the Jewish leaders asked one another, "Where does this man intend to go that we won't be able to find him? Surely he's not going to the Dispersion among the Greeks and teach the Greeks, is he?

"Surely our Law does not condemn a person without first hearing from him and finding out what he is doing, does it?"

The Jewish leaders replied to him, "Surely we're right in saying that you are a Samaritan and have a demon, aren't we?"

But some of them said, "Surely the one who opened the eyes of the blind man could have kept this man from dying, couldn't he?"

They kept looking for Jesus and saying to one another as they stood in the Temple, "What do you think? Surely he won't come to the festival, will he?"
