Abraham is known to be the founder of Judaism, and he founded the religion in Israel about 4000 years ago.
Abraham is considered the father of the Jewish people. Jews see Abraham as a symbol of trusting and obeying God. Abraham is also important to followers of Christianity and of Islam.
Moses is regarded as the most important prophet in Judaism. He acted according to the request of God and freed the Jews from the brutality and slavery they were experiencing under the Pharaoh of Egypt. He was also God's chosen one to receive the Ten Commandments, which were given to him in the form of a stone tablet. The Ten Commandments still hold importance in the world.
