Guttural R
Many Jewish immigrants to Israel spoke a variety of Arabic in their countries of origin and pronounced the Hebrew rhotic as an alveolar tap , similar to Arabic '. Gradually, many of them began pronouncing their Hebrew rhotic as a voiced uvular fricative , a sound similar or (depending on the Arabic dialect) identical to Arabic '. However, in modern Sephardic and Mizrahi poetry and folk music an alveolar rhotic continues to be used.
Biblical Hebrew
Biblical Hebrew ( "Ivrit Miqra'it" or "Leshon ha-Miqra"), also called Classical Hebrew, is an archaic form of Hebrew, a Canaanite Semitic language spoken by the Israelites in the area known as Israel, roughly west of the Jordan River and east of the Mediterranean Sea. The term "Hebrew" was not used for the language in the Bible, which was referred to as ("sefat kena'an", i.e. language of Canaan) or ("Yehudit", i.e. Judaean), but the name was used in Greek and Mishnaic Hebrew texts. It is more or less mutually intelligible with modern Hebrew.
