'Reasoning' in the Bible

And they were reasoning among themselves, saying, We took no bread.

And Jesus, seeing it, said, O you of little faith, why are you reasoning among yourselves, because you have no bread?

The baptism of John, where did it come from? from heaven or from men? And they were reasoning among themselves, saying, If we say, From heaven; he will say to us, Why then did you not have faith in him?
