“In Genesis 31:15, Rachel and Leah complain that their father has been using up ‘the money given for us’. in Bari a phrase for dowry was used and (…) a phrase that is often heard, that ‘he has eaten our dowry.’ This quite often happens to a girl who is in the process of betrothal; if her father is unscrupulous he will arrange a marriage and receive and use up the dowry without giving the girl a proper chance to refuse, unless she is able to repay the money herself. (…) This parallel does not go the whole way, I know, but the idea behind the complaint is similar and very real in Bari.”

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 Jacob.
