EPH 6:9

9 You masters, just like your slaves [should serve you well], you similarly must treat them well. Stop threatening [to beat] them [if they do not do their work well]. Do not forget you and they have the same Lord who is in heaven. [So he is the one who will say to you and your slaves whether he approves of what you and they have done], and [when he judges people], he does not act more favorably [toward some than he acts toward others].
