Who laid the foundation for the nation of yahweh?

The foundation for the nation of Yahweh is primarily attributed to the patriarch Abraham, who is considered the father of the Israelite people and a key figure in Judaism, Christianity, and Islam. His covenant with God established a special relationship between Yahweh and his descendants, leading to the formation of the Israelite nation. This foundation was further solidified through the leadership of figures like Moses, who delivered the Israelites from slavery and received the Law, including the Ten Commandments, which guided their identity as a people dedicated to Yahweh.
