'Woman servant' in the Bible

Laban also gave his woman servant Bilhah to his daughter Rachel to be her maidservant.

So Rachel gave Jacob her woman servant Bilhah to be his wife, and Jacob had sex with her.

When Leah saw that she had stopped bearing children, she took her woman servant Zilpah and gave her to Jacob as a wife.

"When a person has sexual relations with a woman servant who is engaged to another man, but she has not been completely redeemed nor has her freedom been granted to her, there is to be an inquiry, but they won't be put to death, since she has not been freed.

Meanwhile, we also have straw and fodder for our donkeys, and bread and wine for me, for this young woman servant, and for the young man who is with your servants. We don't need anything else."
