'Maid servant' in the Bible

And Sarai Abram's wife did not bear him children. And she had an Egyptian maidservant; and her name was Hagar.

And Sarai said to Abram, Behold now, Jehovah has shut me up, that I do not bear. Go in, I pray thee, to my maidservant: it may be that I shall be built up by her. And Abram hearkened to the voice of Sarai.

And Sarai Abram's wife took Hagar, the Egyptian, her maidservant, at the end of ten years that Abram had dwelt in the land of Canaan, and gave her to her husband Abram, as his wife.

And Sarai said to Abram, My wrong be on thee! I have given my maidservant into thy bosom; and now she sees that she has conceived, I am lightly esteemed in her eyes. Jehovah judge between me and thee!

And Abram said to Sarai, Behold, thy maidservant is in thy hand: do to her what is good in thine eyes. And Sarai oppressed her; and she fled from her face.

And he said, Hagar, Sarai's maidservant, whence comest thou? and whither art thou going? And she said, I am fleeing from the face of my mistress Sarai.

And Laban gave to her Zilpah, his maidservant, to be maidservant to Leah his daughter.

And Laban gave to Rachel his daughter, Bilhah, his maidservant, to be her maidservant.

And she gave him Bilhah her maidservant as wife, and Jacob went in to her.

And Bilhah Rachel's maidservant again conceived, and bore Jacob a second son.

And when Leah saw that she had ceased to bear, she took Zilpah her maidservant and gave her to Jacob as wife.

And Zilpah Leah's maidservant bore Jacob a son.

And Zilpah Leah's maidservant bore Jacob a second son.

And Leah said, God has given me my hire, because I have given my maidservant to my husband; and she called his name Issachar.

And the sons of Bilhah, Rachel's maidservant: Dan and Naphtali.

And the sons of Zilpah, Leah's maidservant: Gad and Asher. These are the sons of Jacob that were born to him in Padan-Aram.

and you have risen up against my father's house this day, and have slain his sons, seventy men on one stone, and have made Abim'elech, the son of his maidservant, king over the citizens of Shechem, because he is your kinsman--

We have straw and provender for our asses, with bread and wine for me and your maidservant and the young man with your servants; there is no lack of anything."

For it is written that Abraham had two sons; one of the maid servant, and one of the free woman.

But he that was of the maid servant was born according to flesh, and he that was of the free woman through the promise.

But what says the scripture? Cast out the maid servant and her son; for the son of the maid servant shall not inherit with the son of the free woman.

So then, brethren, we are not maid servant's children, but children of the free woman.
