'Bondwoman' in the Bible

Therefore she said to Abraham, “Drive out this maid and her son, for the son of this maid shall not be an heir with my son Isaac.”

God said to Abraham, “Do not let it distress you because of Ishmael and your maid; whatever Sarah tells you, listen to her and do what she asks, for your descendants will be named through Isaac.

And I will also make a nation of [Ishmael] the son of the maid, because he is your descendant.”

“If a man sells his daughter to be a female servant, she shall not go free [after six years] as male servants do.

“Six days [each week] you shall do your work, but on the seventh day you shall stop [working] so that your ox and your donkey may settle down and rest, and the son of your female servant, as well as your stranger, may be refreshed.

then take an awl and pierce it through his ear into the door, and he shall [willingly] be your servant always. Also you shall do the same for your maidservant.
