Interpretation of Jewish laws
Mary Douglas offered probably the most cogent interpretation of these laws in her book Purity and Danger (1966). She suggested that these notions of defilement are rules of separation that symbolize and help maintain the biblical notion of the distinctness of the Hebrews from other societies. A central element in her interpretation is that each of the injunctions is prefaced by the command to be holy. This distinction between holiness and “abomination,” Douglas wrote, enables these restrictions to make sense: “Holiness means keeping distinct the categories of creation. It therefore involves correct definition, discrimination, and order.” The dietary laws of Leviticus and Deuteronomy exemplify holiness in this sense. The ancient Hebrews were pastoralists, and cloven-hoofed and cud-chewing hoofed animals are proper food for such people; hence, Douglas maintains, they became part of the social order and were domesticated as slaves. Pigs and camels, however, do not meet the criteria of animals that are fit for pastoralists to consume. As a result, they are excluded from the realm of propriety and are deemed “unclean.” People who eat food that is unclean and “out of place” are themselves unclean and are prohibited from approaching the Temple.
There is, however, another dimension to the food customs enshrined in the Torah. In addition to expressing Israel’s separateness as a nation—membership in which was ascribed by birthright—Israelite food customs also mirrored their internal divisions, which were castelike and were inherited. Although the rules of separation referred primarily to the priests, they also affected the rest of the population. The priest’s inherent separateness from ordinary Israelites was symbolized by the prescription that he had to avoid uncleanness more than anyone else. He was not to drink wine or strong drink, and he had to wash his hands and feet before the Temple service. Explicit in the prescriptions of the Torah is that an offering sanctifies anyone who touches it. Priests were often the only people permitted to consume it.
These rules symbolizing the priestly group’s castelike separateness also validated a system of taxation benefitting them, couched in terms of offerings, sacrifice, and tithes. The religious rationalization of taxation is illustrated in the Hebrew Bible by the “first-fruits” ceremony. Fruit trees were said to live their own life, and they were to remain untrimmed for three years after they were planted. But their fruits could not be enjoyed immediately: God had to be given his share in the first-fruit ceremonies. These first fruits represent the whole, and the entire power of the harvest—which is God’s—is concentrated in them. Sacrifice is centred around the idea of the first-fruits offering. Its rationalization was that everything belonged to God; the central point in the sacrifice is the sanctification of the offering, or the surrender of it to God. Its most immediate purpose was to serve as a form of taxation to the priests; only they were considered holy enough to take possession of it.
