In the Bible, "Simon" refers to several different individuals, but the most notable ones include:

• Simon Peter : Also known simply as Peter, he was one of Jesus' closest disciples and a leader among the twelve apostles. Originally a fisherman, Jesus gave him the name Peter, meaning "rock." He is well-known for his impulsive nature, his declaration of Jesus as the Messiah, and his significant role in the early Christian church after Jesus' resurrection (Matthew 16:16; John 1:42; Acts 10)

• Simon the Zealot : One of the twelve apostles, distinguished by the title "Zealot," which may indicate either his zealous nature or possible association with a Jewish nationalist group. He is mentioned in the lists of apostles in the Gospels and Acts but is otherwise obscure, with little detail about his life or ministry. Tradition holds that he preached in Egypt and Persia and was martyred (Matthew 10:4; Mark 3:18; Luke 6:15; Acts 1:13)

• Simon, brother of Jesus : Mentioned in the Gospels as one of Jesus' brothers, alongside James, Joseph, and Judas. Some traditions suggest he might be the same person as Simeon of Jerusalem, an early church leader (Matthew 13:55; Mark 6:3)

Other Simons mentioned include Simon the leper, Simon of Cyrene (who carried Jesus' cross), Simon Iscariot (father of Judas Iscariot), Simon the sorcerer, and Simon the tanner, but these are less central figures. Thus, "Simon" in the Bible can refer to multiple people, with Simon Peter and Simon the Zealot being the most prominent apostles named Simon.
