Semitic languages
The similarity of the Hebrew, Arabic and Aramaic languages was accepted by Jewish and Islamic scholars since medieval times. The languages were familiar to Western European scholars due to historical contact with neighbouring Near Eastern countries and through Biblical studies, and a comparative analysis of Hebrew, Arabic, and Aramaic was published in Latin in 1538 by Guillaume Postel. Almost two centuries later, Hiob Ludolf described the similarities between these three languages and the Ethiopian Semitic languages. However, neither scholar named this grouping as "Semitic".
Languages of Israel
On 19 July 2018, the Knesset passed a basic law under the title , which defines Hebrew as "the State's language" and Arabic as a language with "a special status in the State" (article 4). The law further says that it should not be interpreted as compromising the status of the Arabic language in practice prior to the enactment of the basic law, namely, it preserves the status quo and changes the status of Hebrew and Arabic only nominally.
