ἀξίως τῶν ἁγίων. In a manner worthy of the saints—as saints should.
παραστῆτε, help; cf. 2Ti 4:17.
ἐν ᾧ ἂν κ.τ.λ. This suggests that Phoebe was going to Rome on her own business, and that S. Paul used the opportunity of sending his letter.
προστάτις. Only here in N.T.; cf. προΐστασθαι, Rom 12:8; 1Th 5:12; 1Ti 5:17; cf. Witkowski, Ep. Priv. 48. 9, ib[316] 9. 4, ‘protectress.’ A word used technically to mean the representative or patron; but here to describe the way in which Phoebe ‘looked after’ any who wanted her help.
