Among the Tonga, the procedure for determining the person who is to assume responsibility for the widow (i.e., to inherit his “name” / ancestral spirit and familial responsibilities) is somewhat more complicated. The primary consideration is not only the “closeness” of the relationship of the potential husband to the deceased (as in the Hebrew), but also his social suitability, which involves a complex of factors; e.g., present marital status, personality, economic ability to support a(nother) wife, etc. The dead man’s relatives (on the mother’s side) would decide upon several possible candidates, and the woman would then be able to select from among them. She might even choose not to get married again, but not normally if she were childless as Ruth was.

There is also a linguistic problem in conveying the concept of “closer” relative. In Chitonga, for example, kinsmen/women are distinguished as being either “nearer” or “farther” in relationship according to an elaborate set of social criteria. Closest are one’s own blood brothers and sisters; these form the mukwasyi as they sit around the same fire fueled by dung from their common herd of cattle. Next are those who are regarded as being equivalent to one’s “father,” “mother,” “brother,” or “sister”; they belong to one’s cikombo or “umbilical cord.” The final group comprising the inner circle of relatives (or “clan,” mukowa) would include all those males who would be allowed to “eat one’s name” (kulya zind), that is, succeed to one’s position upon death. Normally only a man who was in a “brotherly” or “fatherly” relationship to the deceased (on his mother’s side of the family) would be allowed to “inherit” his wife. The great difficulty in this case is that Boaz, being a relative of Elimelech, does not qualify at all according to the Tonga kinship perspective, and therefore the usual terminology cannot be employed. As a musazinyina, or one who would sit around the same fireplace at a funeral, he could legally “marry” Ruth, but he could not enter the place of her dead husband to preserve his line of descent.
