““Deuteronomy’s notion of tithes—that for two out of three years surplus is shared broadly with the disadvantaged, and in the third year is given to them outright—is sound economics when seen in light of conceptions of redistributive economics in primitive societies. In modern capitalist societies, surplus earnings are placed into savings, and insurance policies are taken out to hedge against various forms of adversity. The laws of tithing may be construed as another element in a program of primitive insurance. In a premodern society, A will give some of his surplus in a good year to B, who may have fallen on hard times in exchange for B’s commitment to reciprocate should their roles one day be reversed.””
