ISB ~ Titus 2 v9

slaves:Slavery was an accepted institution in Roman society. Paul did not attack it directly in his letters, but he sought to improve the relationship between masters and slaves and stressed that both stand on an equal footing in Christ (Gal 3:28; Col 3:22-4:1). Here he implies that the dependability of slaves will help to advertise the gospel to the world. See note on Eph 6:5.
