This work looks at the rite presented in Deut 25:5–10 through a sociological framework. As such, it argues that ritual is a social act aimed at protecting communal interests over the interests of its individual members. More specifically, the rite described in Deut 25:5–10 was meant to act as a bulwark against infiltration of tribal land through exogamy. In later periods, it is argued that the focus of the rite narrowed to the priestly class. / text
