See I Cor. 11:20-24], Paul delivered a message that lasted until midnight, [since] he was planning to leave [Troas] the next day. Now there were many lamps in the upstairs room where we were meeting. A certain young man, named Eutychus, fell sound asleep while sitting on an [open] window ledge [during the message]. Since Paul's message continued [until nearly midnight] Eutychus was overcome by sleep and fell from the third floor to his death.read more.
Paul hurried downstairs and placed himself on the young man and held him closely, saying [to the people gathered around], "Do not be upset, he is alive." After that Paul went upstairs, broke bread and ate [a common meal]. [Following the meal] Paul talked with them for a long time, even until it got daylight, and then he left. [In the meantime] they brought the young fellow [back upstairs] alive, and were greatly comforted.
