Ephesians 5:21

Subjecting yourselves to one another (upotassomenoi allhloi). Present middle participle of upotassw, old military figure to line up under ( Colossians 3:18 ). The construction here is rather loose, coordinate with the preceding participles of praise and prayer. It is possible to start a new paragraph here and regard upotassomenoi as an independent participle like an imperative.
