Salute Tryphena and Tryphosa who labour in the Lord. Salute the beloved Persia, which laboured much in the Lord. All these seem to have been Church workers; and the last at least, from the way St. Paul speaks of her, must have been known by him personally, and done work of which he was cognizant.
It is to be observed how, in calling her "the beloved," he avoids, with delicate propriety, adding "my," as he does in speaking of his male friends.
