“Brothers” has to be translated into Naro as “younger brothers and older brothers” (Tsáá qõea xu hẽé / naka tsáá kíí). All brothers are included this way, also because of the kind of plural that has been used.
This also must be more clearly defined in Yucateco as older or younger (suku’un or Iits’in), but here there are both older and younger brothers. Yucateco does have a more general word for close relative, family member.
While in Chinese there is also a differentiation between younger and older brother (didi 弟弟 vs. gege 哥哥”), the term dixiong 弟兄 or xiongdi 兄弟 is used as the unspecific plural form for “brothers” in these cases.
Many languages distinguish between inclusive and exclusive first-person plural pronouns (“we”). The inclusive “we” specifically includes the addressee (“you and I and possibly others”), while the exclusive “we” specifically excludes the addressee (“he/she/they and I, but not you”). This grammatical distinction is called “clusivity.” While Semitic languages such as Hebrew or most Indo-European languages such as Greek or English do not make that distinction, translators of languages with that distinction have to make a choice every time they encounter “we” or a form thereof (in English: “we,” “our,” or “us”).
For this verse, the Jarai and the Adamawa Fulfulde translation both use the exclusive pronoun, excluding Joseph.
Like many languages (but unlike Greek or Hebrew or English), Spanish uses a formal vs. informal second-person pronoun (a familiar vs. a respectful “you”). Spanish Bibles all use only the informal second-person pronoun (tú), with the exception of Dios Habla Hoy (DHH) (third edition: 1996) which also uses the formal pronoun (usted). In the referenced verses, the formal form is used.
