1 Timothy 6:1-10 (ESV)
6:1 Let all who are under a yoke as slaves  regard their own masters as worthy of all honor, so that the name of God and the teaching may not be reviled. 2 Those who have believing masters must not be disrespectful on the ground that they are brothers; rather they must serve all the better since those who benefit by their good service are believers and beloved.
False Teachers and True Contentment
Teach and urge these things. 3 If anyone teaches a different doctrine and does not agree with the sound  words of our Lord Jesus Christ and the teaching that accords with godliness, 4 he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions, 5 and constant friction among people who are depraved in mind and deprived of the truth, imagining that godliness is a means of gain. 6 Now there is great gain in godliness with contentment, 7 for we brought nothing into the world, and  we cannot take anything out of the world. 8 But if we have food and clothing, with these we will be content. 9 But those who desire to be rich fall into temptation, into a snare, into many senseless and harmful desires that plunge people into ruin and destruction. 10 For the love of money is a root of all kinds of evils. It is through this craving that some have wandered away from the faith and pierced themselves with many pangs.
