'Domestic' in the Bible

And Abram saith, 'Lo, to me Thou hast not given seed, and lo, a domestic doth heir me.'

'No domestic is able to serve two lords, for either the one he will hate, and the other he will love; or one he will hold to, and of the other he will be heedless; ye are not able to serve God and mammon.'

Thou -- who art thou that art judging another's domestic? to his own master he doth stand or fall; and he shall be made to stand, for God is able to make him stand.
