I used the word ארנבת for rabbit. It also translates as 'hare'. [Wikipedia](https://en.wikipedia.org/wiki/Hare) says 'Hares are classified in the same family as rabbits'.  

I used [this concordance](http://www.snopi.com/xDic/Bible.aspx) to search Tanach and found two references:
ויקרא

[פרק יא' פסוק ו']
וְאֶת-הָאַרְנֶבֶת כִּי-מַעֲלַת גֵּרָה הִוא וּפַרְסָה לֹא הִפְרִיסָה טְמֵאָה הִוא לָכֶם 

דברים

[פרק יד' פסוק ז']
אַךְ אֶת-זֶה לֹא תֹאכְלוּ מִמַּעֲלֵי הַגֵּרָה וּמִמַּפְרִיסֵי הַפַּרְסָה הַשְּׁסוּעָה אֶת-הַגָּמָל וְאֶת-הָאַרְנֶבֶת וְאֶת-הַשָּׁפָן כִּי-מַעֲלֵה גֵרָה הֵמָּה וּפַרְסָה לֹא הִפְרִיסוּ טְמֵאִים הֵם לָכֶם 

The Gemoro mentions the rabbit. 

[Megillah 9a](https://www.sefaria.org/Megillah.9a.11?ven=William_Davidson_Edition_-_English&vhe=William_Davidson_Edition_-_Vocalized_Aramaic&lang=bi&with=all&lang2=en ) reports

> King Ptolemy once gathered 72 Elders. He placed them in 72 chambers,
> each of them in a separate one, without revealing to them why they
> were summoned. He entered each one's room and said: "Write for me the
> Torah of Moshe, your teacher". God put it in the heart of each one to
> translate identically as all the others did.

The Elders amended the text to prevent problems. One of these [was](https://www.sefaria.org/Megillah.9b.3?ven=William_Davidson_Edition_-_English&vhe=William_Davidson_Edition_-_Vocalized_Aramaic&lang=bi&with=all&lang2=en) :

> And in the list of unclean animals they wrote for him: The
> short-legged beast [tze’irat haraglayim]. And they did not write for
> him: “And the hare [arnevet]” (Leviticus 11:6), since the name of
> Ptolemy’s wife was Arnevet, so that he would not say: The Jews have
> mocked me and inserted my wife’s name in the Torah. Therefore, they
> did not refer to the hare by name, but by one of its characteristic
> features.
