Luke"s reference to the many lamps (Gr. lampades hikani, lit. many torches) suggests that it was the combination of a long message and lack of oxygen that caused Eutychus to fall asleep. The Greek word translated "young man" (meanias) elsewhere describes a boy of eight to14years old. However, his name suggests that he may have been a slave, in which case he could have been in his thirties. [1] Doctor Luke pronounced Eutychus (lit. fortunate) dead. [source][source][source]
"The length of Paul"s preaching may incline us to sympathize with sleepy Eutychus. The well-developed synoptic theme of wakefulness puts a different perspective on the matter. Falling asleep is a serious failure with potentially grave consequences. Paul"s dedicated preaching makes demands on his audience. They must be dedicated listeners who hear the word and "bear fruit with perseverance (en upomone)" ( Luke 8:15). Eutychus failed and fell." [2][source]
"I confess that Paul"s experience has always been a comfort to me. When I look out at the congregation and see some brother or sister out there sound asleep, I say to myself, "It"s all right. Just let them sleep. Paul put them to sleep, too."" [3][source]
