Hebr 9:1-14 The author compares the first covenant agreement (literally the Old Testament) to the New Covenant agreement (literally the “New Testament”). The Mosaic covenant (Ex 19-24; deuteronomy; Joshua 24) is like another type of ancient covenant, the “political treaty” between a powerful king and his weaker vassal. In the form of such treaties, God, the Overlord, Israel, reminds the vassals how God saved him, and Israel then accepts the federal rules. Israel is promised a blessing for obedience and a curse for the breaking of obedience. An alliance in its most general and historical sense is a solemn promise to participate or refrain from participating in a particular act. A covenant is a type of agreement that meets a contractual condition. The ally promises an alliance to do something (affirmative alliance) or not to do it (negative alliance). The New Covenant is a biblical interpretation, partly derived from a sentence in the book of Jeremiah (Jeremiah 31:31) in the Hebrew Bible. There are several Christian eschatologies that define the New Covenant. For example, an initiated eschatology defines and describes the New Covenant as an ongoing relationship between Christian believers and God, which will be full of fruit after the Second Coming of Christ; This means that it will be full of fruit not only in believing hearts, but also in the future outside world.
[Citation required] The connection between the blood of Christ and the New Covenant is seen in most modern English translations of the New Testament with the proverb: “This cup that is poured out for you is the new covenant in my blood.”  In religion, a formal covenant or agreement that God has made with a religious community or with humanity in general. The concept, central to the Abrahamic religions, derives from biblical covenants, especially the Abrahamic covenant. That is why you come, let us make a covenant, me and you; And leave it for a testimony between me and you. This is what many doctors want – and many have begun to reclaim the alliance between doctor and patient. The Mosaic covenant refers to a biblical covenant between God and the biblical Israelites.   The foundation and provisions of the Mosaic Covenant are recorded in the first five books of the Hebrew Bible, traditionally attributed to the Mosaic author and called together torah, and this covenant is sometimes called the Law of Moses or the Mosaic Law or mitzvot of 613. In every sense of the word, a treaty. In the Bible (see also the Bible), an agreement between God and His people, in which God makes promises to His people and usually requires them to behave in a particular way.
In the Old Testament, God made agreements with Noah, Abraham, and Moses. He promised Noah that he would never again destroy the Earth by a flood. He promised Abraham to become the ancestor of a great nation, provided that Abraham went to the place that God had shown him and sealed the covenant by circumcision of all the men of the nation. God told Moses that the Israelites would reach the Promised Land, but that they had to obey the Mosaic law. In the New Testament, God promised salvation to those who believe in Jesus (see also redemption). To distinguish Him from God`s eternal covenant with mankind, Bahá`í refers to the agreement of a manifestation with His followers, to whom to turn and obey them immediately after His death as an inferior covenant.  Two peculiarities of the Bahá`í Covenant, which within the Bahá`í Faith is called the Bahá`u`lláh Covenant, are explicit and are also communicated in certified written documents.  The Bahá`u`lláh Confederacy considers bahá`u`lláh`s covenant to be unique in the history of religion and to be the most powerful means of ensuring the mental health of followers of the faith, their permanent unity, and their full protection from all efforts to stir up discord or create divisions.  In the Latter-day Saint movement, a covenant is a promise made between God and a person or group of men.  God sets the conditions for the covenant, and when the conditions are met, He blesses the person who made the covenant and kept it. .
