1 Timothy 6:1-5

Let as many as are servants under the yoke count their own masters worthy of all honor, that the name of God and the doctrine be not blasphemed. And they that have believing masters, let them not despise them, because they are brethren; but let them serve them the rather, because they that partake of the benefit are believing and beloved. These things teach and exhort. If any man teacheth a different doctrine, and consenteth not to sound words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness; he is puffed up, knowing nothing, but doting about questionings and disputes of words, whereof cometh envy, strife, railings, evil surmisings, wranglings of men corrupted in mind and bereft of the truth, supposing that godliness is a way of gain.
