{In the house} (en t(8869) oiki(8369)). Probably Peter's house in
Capernaum which was the home of Jesus when in the city. {What
were ye reasoning in the way?} (Ti en t(8869) hod(9369)
dielogiszethe;). Imperfect tense. They had been disputing (verse
 34 ), not about the coming death of the Master, but about the
relative rank of each of them in the political kingdom which they
were expecting him to establish. Jesus had suspected the truth
about them and they had apparently kept it up in the house. See
on 烘t 18:1| where the disciples are represented as bringing the
dispute to Jesus while here Jesus asks them about it. Probably
they asked Jesus first and then he pushed the matter further and
deeper to see if this had not been the occasion of the somewhat
heated discussion on the way in.
