Eu′ty·chus was "A young man in Troas who is the last person
reported in the Scriptures to have been miraculously restored to
life. Upon Paul's visit to Troas on his third missionary tour, he
prolonged his discourse to the brothers until midnight. Overcome by
tiredness and possibly by the heat of the many lamps and the
crowded condition in the upper chamber, Eutychus fell into deep
sleep and tumbled down from a third-story window. The physician
Luke, the writer of Acts and apparently an eyewitness of what
happened, reports that Eutychus was not merely unconscious but "was
picked up dead." Following a procedure similar to that of Elisha in
resurrecting the Shunammite's son, Paul threw himself upon Eutychus
and embraced him. Paul's words, "Stop raising a clamor, for his
soul is in him," indicated that life had been restored to
Eutychus.-Ac 20:7-12; see also 2Ki 4:34."
