2 John 1:8

μισθόν, cf. Matthew 20:8; James 5:4. St. John here addresses not only Kyria but her family and “the Church in her house”. He views them as his fellow-labourers in the Lord's vineyard: “We have worked together (ἠργασάμεθα): see that you do not forfeit the reward of your labour. Get a full wage. Be not like workmen who toward the close of the day fall off, doing their work hadly or losing time, and get less than a full day's pay.” ἀπολέσητε … ἠργασάμεθα … ἀπολάβητε : “We have been fellow-workers thus far, and I mean to be faithful to the last; see that you also be so”. Their danger lay in taking up with false teaching and losing the comfort of the Gospel in its simplicity and fulness.
