{We bring you good tidings of the promise} (h(886d)eis hum(8373)
euaggelizometha t(886e) epaggelian). Two accusatives here (person
and thing), old Greek did not use accusative of the person with
this verb as in  16:10  Lu 3:18 . Note "we you" together. Here
the heart of Paul's message on this occasion.
