In the course of our history JHWH has made many promises to us, humans, and has made very clear arrangements with mankind on more than ten occoasions. These arrangements always have the form of agreements, treaties and contracts. In the case of all these arrangements, agreements, treaties or contracts there are always two parties involved: God on the one side and a group of people or even all mankind on the other side.
