'Sister' in the Bible

And I said after she had done all these things, Turn thou unto me. But she returned not. And her treacherous sister Judah saw it.

And I saw, when for all the causes whereby backsliding Israel committed adultery I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also.

And yet for all this her treacherous sister Judah hath not turned unto me with her whole heart, but feignedly, saith the LORD.

Therefore thus saith the LORD concerning Jehoiakim the son of Josiah king of Judah; They shall not lament for him, saying, Ah my brother! or, Ah sister! they shall not lament for him, saying, Ah lord! or, Ah his glory!
