The Old Testament stresses the special relationship between God and his chosen people, Israel, but includes instructions for proselytes as well. This relationship is expressed in the biblical covenant (contract) between the two, received by Moses. The law codes in books such as Exodus and especially Deuteronomy are the terms of the contract: Israel swears faithfulness to God, and God swears to be Israel's special protector and supporter. "The Jewish Study Bible" denies that covenant means contract.
