<p>16:12 <i>Greet Tryphaena and Tryphosa, who labour in the Lord. Greet Persis the beloved, who laboured much in the Lord- </i>The two sisters were labourers in the Lord, but sister Persis is commended for labouring much. The aorist may refer to some special occasion in the past, some particular great work she had done. Or maybe she had lost her labouring zeal and therefore laboured no more, or was too infirm to do the kind of labour she had once done.</p>
