All who are under the yoke of slavery should consider their masters worthy of full respect, so that God's name and our teaching may not be slandered. Those who have believing masters are not to show less respect for them because they are brothers. Instead, they are to serve them even better, because those who benefit from their service are believers, and dear to them. These are the things you are to teach and urge on them.

(1 Timothy 6:1-2, NIV)
