Covenant. An agreement, contract, or written promise between two individuals that frequently constitutes a pledge to do or refrain from doing something. The individual making the promise or agreement is known as the covenantor, and the individual to whom such promise is made is called the covenantee.
The new covenant is distinguished from the older covenant in four ways: (1) God will write the law in the minds and on the hearts of those in the new covenant; (2) God will be the God of those in the new covenant and they will be his people; (3) those in the new covenant will know God; (4) God will forgive the iniquities and the sins of those in the new covenant.
