The Bible contains several passages that address the relationship between slaves and masters. Here are some examples:
* Ephesians 6:5-8: "Slaves, obey your earthly masters with respect and fear, and with sincerity of heart, just as you would obey Christ. Obey them not only to win their favor when their eye is on you, but as slaves of Christ, doing the will of God from your heart. Serve wholeheartedly, as if you were serving the Lord, not people, because you know that the Lord will reward each one of you for whatever good you do, whether you are slave or free."
* Colossians 3:22-24: "Slaves, obey your earthly masters in everything; and do it, not only when their eye is on you and to win their favor, but with sincerity of heart and reverence for the Lord. Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving."
* 1 Timothy 6:1-2: "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 should not show them disrespect just because they are fellow believers. Instead, they should serve them even better because their masters are dear to them as fellow believers and are devoted to the teaching of the gospel. These are the things you are to teach and urge on them."
* Titus 2:9-10: "Teach slaves to be subject to their masters in everything, to try to please them, not to talk back to them, and not to steal from them, but to show that they can be fully trusted, so that in every way they will make the teaching about God our Savior attractive."
* 1 Peter 2:18-20: "Slaves, in reverent fear of God submit yourselves to your masters, not only to those who are good and considerate, but also to those who are harsh. For it is commendable if someone bears up under the pain of unjust suffering because they are conscious of God. But how is it to your credit if you receive a beating for doing wrong and endure it? But if you suffer for doing good and you endure it, this is commendable before God."
