'Sister' in the Bible

Three sons of Zeruiah [the half sister of David] were there: Joab, Abishai, and Asahel. Now Asahel was as light and swift-footed as one of the [wild] gazelles in the field.

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 for his sister Tamar; for she was a virgin; and Amnon thought it hard for him to do any thing to her.

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

And Absalom spake unto his brother 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 slain 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 made Amasa captain of the host instead of Joab: which Amasa was a man's son, whose name was Ithra an Israelite, that went in to Abigail the daughter of Nahash, sister to Zeruiah Joab's mother.

And the king took the two sons of Rizpah the daughter of Aiah, whom she had borne to Saul, Armoni and Mephibosheth; and the five sons of the sister of Michal the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite;
