The Tanakh (Jewish Bible).
The most important part of Jewish life is the observance of the Torah and its commandments, known as mitzvot. These teachings guide Jewish beliefs, values, and practices, shaping their relationships with God, community, and the world around them. Additionally, community and family play significant roles in Jewish life, fostering social connections and support networks.
The most important apostles in the Bible were Peter, Paul, and John. Peter was a leader among the apostles and played a key role in spreading Jesus' teachings to the Jewish community. Paul, originally a persecutor of Christians, became a prominent missionary to the Gentiles, spreading the message of Jesus to non-Jewish communities. John, known as the beloved disciple, wrote several books of the New Testament and played a significant role in spreading the teachings of Jesus through his writings and teachings.
