Laid down their own necks (ton eautwn tracelon upeqhkan). First aorist active of upotiqhmi, old verb to place under (the axe of the executioner), only here in N.T. in this sense, though in 1 Timothy 4:16 to suggest. If literal or figurative, the incident may be connected with the uproar created by Demetrius in Ephesus. Certainly Paul felt deep obligation toward them (see Acts 20:34 ). Not only I (ouk egw mono). Rather, "not I alone" (adjective mono). The Gentile churches also (great mission workers).
