Jamieson, Fausset & Brown

Salute Tryphena and Tryphosa, who labour in the Lord--two active women. Salute the beloved Persis--another woman. which laboured much in the Lord--referring probably, not to official services, such as would fall to the deaconesses, but to such higher Christian labors--yet within the sphere competent to woman--as Priscilla bestowed on Apollos and others (Act 18:18).
