{Laid down their own necks} (	on heaut(936e) trachelon
hupeth(886b)an). First aorist active of hupotith(886d)i, old verb to
place under (the axe of the executioner), only here in N.T. in
this sense, though in  1Ti 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  Ac 20:34 ). {Not only I} (ouk eg(9320)monos).
Rather, "not I alone" (adjective monos). The Gentile churches
also (great mission workers).
