'Domestic' in the Bible

No domestic slave is able to serve two masters, for either he will hate the one and love the other, or he will be devoted to one and will despise the other. You are not able to serve God and money."

Who are you, who passes judgment on the domestic slave belonging to someone else? To his own master he stands or falls, and he will stand, for the Lord is able to make him stand.

Domestic slaves, be subject to your masters with all respect, not only to those [who are] good and gentle, but also to those [who are] unjust.
