Aramaic
In Aramaic, the prefix bar- means "son" and is used as a prefix meaning "son of". In the Bible, Peter is called Bar-jonah in Matthew 16:17 and Nathanael is possibly called Bartholomew because he is the son of Tolmai. The titles can also be figurative, for example in Acts 4:36-37 a man named Joseph is called Barnabas meaning son of consolation.
Jewish usage
For more details on this topic, see Jewish name.
Jews have historically used Hebrew patronymic names. In the Jewish patronymic system the first name is followed by either ben- or bat- ("son of" and "daughter of", respectively), and then the father's name. (Bar-, "son of" in Aramaic, is also seen). Permanent family surnames exist today but only gained popularity among Sephardic Jews in Iberia and elsewhere as early as the 10th or 11th century and did not spread widely to the Ashkenazic Jews of Germany or Eastern Europe until much later. While Jews now have permanent surnames for everyday life, the patronymic form is still used in religious life. It is used in synagogue and in documents in Jewish law such as the ketubah (marriage contract). Many Sephardic Jews used the Arabic ibn instead of bat or ben when it was the norm. The Spanish family Ibn Ezra is one example.
Many immigrants to the modern Israel Hebraized their names. This was especially common among Ashkenazic immigrants, because most of their names were taken later and some were imposed by the German and Austro-Hungarian Empires.
A popular form to create a new family name using Jewish patronymics sometimes related to poetic Zionist themes, such as ben Ami ("son of my people"), or ben Artzi ("son of my country"), and sometimes related to the Israeli landscape, such as bar Ilan ("son of the trees").
Και για το

In Arabic, the word "ibn" (ابن) (or بن: "bin", "ben" and sometimes "ibni" and "ibnu" to show the final declension of the noun) is the equivalent of the "-son" suffix discussed above (The prefix ben- is used similarly in Hebrew). In addition, "bint" (بنت) means "daughter of". Thus, for example, "Ali ibn `Amr" means "Ali son of `Amr". In Classical Arabic, the word ibn is written as bn between two names, since the case ending of the first name then supplies a vowel. Consequently, ibn is often written as "b.", as bint is often written as "bt.," in name formulas rendered from Arabic into Roman characters. Thus Hisham ibn al-Kalbi is alternatively written as Hisham b. al-Kalbi. However, the pronunciation "bin" is dialectal and has nothing to do with either the spelling or pronunciation in Classical Arabic. The word "Abu" ("Aba" or "Abi" in different declensions) means "father of", so "Abu `Ali" is another name for "`Amr". In medieval times, an illegitimate child of unknown parentage would sometimes be termed "ibn Abihi", "son of his father" (notably Ziyad ibn Abihi.) In the Qur'an, Jesus (Isa in Arabic) is consistently termed "`Isa ibn Maryam" - a matronymic (in the Qur'an, Jesus has no father; see Islamic view of Jesus). An Arabic patronymic can be extended as far back as family tree records will allow: thus, for example, Ibn Khaldun gives his own full name as "`Abd ar-Rahman ibn Muhammad ibn Muhammad ibn Muhammad ibn al-Hasan ibn Muhammad ibn Jabir ibn Muhammad ibn Ibrahim ibn `Abd ar-Rahman ibn Khaldun".
