In the ancient Near East, the “heart” is the center of memory and decision-making, and in Mesopotamian extispicy, the “liver” is the “tablet of the gods” on which the gods inscribe a “true verdict,” providing basic guidance for the people. In international treaties, and especially in Assyrian treaties, emphasis is placed on the importance of “full-hearted” loyalty to the suzerain, going beyond mere “lip service.” The Egyptian “Book of the Dead” likewise emphasizes the central importance of the true testimony of the heart as decisive in the dangerous transit to the afterlife, to becoming an Osiris. These sources combine to emphasize the ultimate commitment expressed by the reference in Jeremiah 31:33 to God’s forthcoming “new covenant” which God will write on the hearts of the people. This is, as it were, a “programming” which transforms them in such a way that they will, by inner necessity, be a loyal people, submitting themselves to God’s guidance and protection.
