To be in subjection to rulers, to authorities, to be obedient (αρχαις εξουσιαις υποτασσεσθα πειθαρχειν). Remarkable double asyndeton, no κα (and) between the two substantives or the two verbs. Πειθαρχειν (to obey), old verb (from πειθομαι, αρχη), in N.T. only here and Acts 27:21.

To be ready unto every good work (προς παν εργον αγαθον ετοιμους εινα). Pauline phrase (2. Corinthians 9:8; 2. Timothy 2:21; 2. Timothy 3:17), here adjective ετοιμος (2. Corinthians 9:5), there verb.
