'Slave girl' in the Bible

she told Abraham, "Throw out this slave girl, along with her son, because this slave's son will never be a co-heir with my son Isaac!"

but God told Abraham, "Don't be troubled about the youth and your slave girl. Pay attention to Sarah in everything she tells you, because your offspring are to be named through Isaac.

Nevertheless, I will make the slave girl's son into a nation, since he, too, is your offspring."

and all the firstborn in the land of Egypt will die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the slave girl who operatesthe hand mill, along with the firstborn of the animals.

Once, as we were going to the place of prayer, we met a slave girl who had a spirit of fortune-telling and who had brought her owners a great deal of money by predicting the future.
