Colossians 4:1

ἰσότητα. The literal meaning is “equality,” and Meyer takes it so here (so Ol., Haupt), explaining not of equality conferred by emancipation, but of the treatment of the slave by his master as a brother in Christ. It may, in spite of Oltramare's denial, mean “equity,” and the combination with δίκ. suggests this meaning here. The master should regulate his treatment of his slave not by caprice, but by equity. παρέχεσθε : “supply on your part,” a dynamic middle.
