Colossians 3:22-25 (King James Version)

 ²²Servants, obey in all things your masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God;

 ²³And whatsoever ye do, do it heartily, as to the Lord, and not unto men;

 ²⁴Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.

 ²⁵But he that doeth wrong shall receive for the wrong which he hath done: and there is no respect of persons.
