New American Standard Bible (NASB)
Colossians 3
22 Slaves, in all things obey those who are your masters on earth, not with external service, as those who merely please men, but with sincerity of heart, fearing the Lord.
23 Whatever you do, do your work heartily, as for the Lord rather than for men,
24 knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve.
25 For he who does wrong will receive the consequences of the wrong which he has done, and that without partiality.
Colossians 4
1 Masters, grant to your slaves justice and fairness, knowing that you too have a Master in heaven.
2 Devote yourselves to prayer, keeping alert in it with an attitude of thanksgiving;
3 praying at the same time for us as well, that God will open up to us a door for the word, so that we may speak forth the mystery of Christ, for which I have also been imprisoned;
4 that I may make it clear in the way I ought to speak.
5 Conduct yourselves with wisdom toward outsiders, making the most of the opportunity.
6 Let your speech always be with grace, as though seasoned with salt, so that you will know how you should respond to each person.
7 As to all my affairs, Tychicus, our beloved brother and faithful servant and fellow bond-servant in the Lord, will bring you information.
