'Sister' in the Bible

And it came to pass after this, that Absalom the son of David had a fair sister, whose name was Tamar; and Amnon the son of David loved her.

And Amnon was so vexed that he fell sick because of his sister Tamar; for she was a virgin; and it seemed hard to Amnon to do anything unto her.

And he said unto him, Why, O son of the king, art thou thus lean from day to day? wilt thou not tell me? And Amnon said unto him, I love Tamar, my brother Absalom's sister.

And Jonadab said unto him, Lay thee down on thy bed, and feign thyself sick: and when thy father cometh to see thee, say unto him, Let my sister Tamar come, I pray thee, and give me bread to eat, and dress the food in my sight, that I may see it, and eat it from her hand.

So Amnon lay down, and feigned himself sick: and when the king was come to see him, Amnon said unto the king, Let her sister Tamar come, I pray thee, and make me a couple of cakes in my sight, that I may eat from her hand.

And when she had brought them near unto him to eat, he took hold of her, and said unto her, Come, lie with me, my sister.

And Absalom her brother said unto her, Hath Amnon thy brother been with thee? but now hold thy peace, my sister: he is thy brother; take not this thing to heart. So Tamar remained desolate in her brother Absalom's house.

And Absalom spake unto Amnon neither good nor bad; for Absalom hated Amnon, because he had forced his sister Tamar.

And Jonadab, the son of Shimeah, David's brother, answered and said, Let not my lord suppose that they have killed all the young men the king's sons; for Amnon only is dead; for by the appointment of Absalom this hath been determined from the day that he forced his sister Tamar.

And Absalom set Amasa over the host instead of Joab. Now Amasa was the son of a man, whose name was Ithra the Israelite, that went in to Abigal the daughter of Nahash, sister to Zeruiah, Joab's mother.
