'Masters' in the Bible

"No one 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 despise the other. You are not able to serve God and money.

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."

Slaves, obey your earthly masters with fear and trembling, in the sincerity of your heart, as to Christ,

And masters, do the same [things] to them, giving up threats, knowing that both their Lord and yours is in heaven, and there is no partiality with him.

Slaves, obey your {human} masters in everything, not {while being watched}, as people pleasers, but with sincerity of heart, fearing the Lord.

Masters, grant your slaves justice and fairness, knowing that you also have a master in heaven.

All those who are under the yoke as slaves must regard their own masters as worthy of all honor, lest the name of God and the teaching be slandered.

And those who have believing masters must not look down on [them] because they are brothers, but rather they must serve, because those who benefit by their service are believers and dearly loved.

Slaves must be subject to their own masters in everything, to be well-pleasing, not to talk back,

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.
