Concerning a good deed done to an impotent man (epi euergesiai anqrwpou asqenou). Objective genitive. Note euergesia (old word, in the N.T. only here and 1 Timothy 6:2 ), as a benefactor, not a malefactor. Skilful turn made by Peter. Is made whole (seswstai). Perfect passive indicative of swzw, stands whole.
