In 'The Sacrificial Service: Gestures of Flesh and Spirit,' Jonathan Grossman, a professor at Bar-Ilan University, reexamines the sacrificial system outlined in Leviticus, arguing that it is a nuanced language of gestures rather than a relic of pagan practices or mere ritualistic commands. He emphasizes that the first word in Leviticus is an invitation, not a command, and that the term 'korban' suggests an approach to God. Grossman redefines the verb 'hiktir' from 'to burn' to 'to transform,' indicating that sacrifices are meant to elevate rather than destroy. He highlights the theological implications of the structure of Leviticus, noting that the first section addresses all Israelites while the second is directed at priests, signifying inclusivity. The distinctions between male and female offerings reflect different relational dynamics with the divine, where male offerings denote reverence and female offerings convey intimacy. The book also revisits the story of Nadav and Avihu, suggesting their actions stemmed from a misdirected zeal rather than recklessness. Grossman's work invites readers to rediscover the rich meanings embedded in Leviticus, transforming it from a text of obligation to one of profound significance.
