A.T. Robertson Commentary Ephesians 5:21

"subjecting yourselves one to another in the fear of Christ." — Ephesians 5:21 (ASV)

Subjecting yourselves to one another (υποτασσομενο αλληλοις). Present middle participle of υποτασσω, 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 υποτασσομενο as an independent participle like an imperative.
