See Poole on "1 Thessalonians 10:31". There were not three months elapsed since the Jews had so sought to have stoned him, and there was no reason for him to think that their fury was in any whit abated. We read in the other evangelists of other words they used (Peter especially, Matthew 16:22), to dissuade our Saviour from this journey to Jerusalem. They were afraid for their Master, and they were afraid also for themselves.
