'Sister' in the Bible
Thou art the daughter of thy mother that loathed her husband and her children; and thou art the sister of thy sisters, who loathed their husbands and their children. Your mother was a Hittite, and your father an Amorite.
And thine elder sister is Samaria that dwelleth at thy left hand, she and her daughters; and thy younger sister, that dwelleth at thy right hand, is Sodom and her daughters.
As I live, saith the Lord Jehovah, Sodom thy sister hath not done, she nor her daughters, as thou hast done, thou and thy daughters!
Behold, this was the iniquity of thy sister Sodom: pride, fulness of bread, and careless ease was in her and in her daughters, but she did not strengthen the hand of the poor and needy.
Yea, Sodom thy sister was not mentioned by thy mouth in the day of thy pride,
And one hath committed abomination with his neighbour's wife; and another hath lewdly defiled his daughter-in-law; and another in thee hath humbled his sister, his father's daughter.
And their names were Oholah the elder, and Oholibah her sister; and they were mine, and they bore sons and daughters. As for their names: Samaria is Oholah, and Jerusalem Oholibah.
And her sister Oholibah saw this, and was more corrupt in her passion than she, and in her fornications more than the whoredoms of her sister.
And she discovered her whoredoms, and discovered her nakedness; and my soul was alienated from her, like as my soul was alienated from her sister.
Thou hast walked in the way of thy sister; and I have given her cup into thy hand.
Thou shalt be filled with drunkenness and sorrow, with the cup of astonishment and desolation, the cup of thy sister Samaria;
And they shall come at no dead person to become unclean; but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may become unclean.
