In Esther, Mordechai identifies himself as of the Tribe of Benjamin and a Jewish man - ish Yehudi, presumably to clarify his allegiance to the Kingdom of Judah as opposed to being of earlier Exiles from the Northern Kingdom.

Jer. 34:9 KJV seems true to the Hebrew original:

“That every man should let his manservant, and every man his maidservant, being an Hebrew or an Hebrewess [Ivri and Ivriyah] go free; that none should serve himself of them, to wit, of a Jew [Yehudi] his brother.”

[Verginius Rufus]

Interesting. The Septuagint renders that as Beniamin and Ioudaios

St. Paul also claimed to be of the tribe of Benjamin, but also referred to himself as a Jew and as a Hebrew.

I knew that "ish" meant "man" because of the name of Saul's son Ishbaal. I once met an Israeli whose surname was Ish-Shalom.
