'Bondslave' in the Bible

Let my wife grind [meal, like a bond slave] for another [man],And let others kneel down over her.

And Mary said, “Behold, the bondslave of the Lord; may it be done to me according to your word.” And the angel departed from her.

“For He has had regard for the humble state of His bondslave;For behold, from this time on all generations will count me blessed.

Epaphras, who is one of your number, a bondslave of Jesus Christ, sends you his greetings, always laboring earnestly for you in his prayers, that you may stand perfect and fully assured in all the will of God.
