Colossians 3:22-24

22Bondmen, obey in all things your masters according to flesh; not with eye-services, as men-pleasers, but in simplicity of heart, fearing the Lord.

23Whatsoever ye do, labour at it heartily, as [doing it] to the Lord, and not to men;

24knowing that of [the] Lord ye shall receive the recompense of the inheritance; ye serve the Lord Christ.
