The covenant between God and the Jews is the basis of the idea of the Jews as the chosen people. The Mosaic Alliance or the Mosellan Law, which Christians, unlike the New Covenant, generally call « the Old Covenant, » played an important role in the organization of Christianity. It was the source of serious quarrels and quarrels that could be seen in Jesus` controversy over the law during his sermon on the mountain, the controversy of circumcision in early Christianity and the antiochian incident, which led the scholar to challenge the relationship between Paul of Tarsus and Judaism. The Book of Acts of the Apostles says that Stephen, the first Christian martyr, was killed after the Ascension of Jesus while he was accused of opposing the temple of Jerusalem and the Mosaic Law.  Later, the Council of Jerusalem dealt in Acts 15:1-21 with the controversy of circumcision in Primitian Christianity. The concept of a union began long before the biblical era, especially the beginnings of Israel. After George E. Mendenhall, alliances were originally created as legal customs and then imitated in the field of religion. These covenants were made on the basis of an oath, a promise between two parties and a subsequent fulfillment.
Participation in an oath implies that the most powerful party would ensure that the other party would receive an appropriate sanction if it was insolvent. In the case of religion, the gods would carry out the punishment. Such covenants have ensured that either blessings or curses are avoided in response to circumstances. The original covenant between God and Abraham follows the form of Theuzerain`s covenant; What is important is that Israel has no duty to stand; Confederation is not subject to conditions. Future alliances between Israel and God would be conditional. This is clearly expressed in Deuteronomy 11:13-21, recited twice a day as part of the basic prayer, the Shema. This section explains that as long as Israel is faithful to God, it will be blessed by bountiful harvests, but if it follows other gods, the country will not support him.
