For instance, Hebrew has no inclusive form for they. The word can be either they masculine or they feminine. In English we have a they which can be either masculine or feminine. So we need to look for a signal in the biblical text for whether they means they masculine or they inclusive. Then we have to express the meaning appropriately in English.
