covenant
Literally, a contract. In the Bible, an agreement between God and his people, in which God makes promises to his people and, usually, requires certain conduct from them. In the Old Testament, God made agreements with Noah, Abraham, and Moses. To Noah, he promised that he would never again destroy the Earth with a flood. He promised Abraham that he would become the ancestor of a great nation, provided Abraham went to the place God showed him and sealed the covenant by circumcision of all the males of the nation. To Moses, God said that the Israelites would reach the Promised Land but must obey the Mosaic law. In the New Testament, God promised salvation to those who believe in Jesus.
