One thought:
They were all Jewish. Jesus was sent only to 'the lost sheep of Israel' (Matthew 15:24), then later he sent his followers to preach to the 'nations'(Acts 1:8)(Matthew 28:19)(Acts 10:1-35) .
Additional Comment:
The Sceptre Promise of a Savior was placed upon Judah (nicknamed Jews) by Israel, his father. At the time of Christ, the Northern Kingdom of Israel was captive and dispersed by the Assyrian Empire in 722-718 BC, never to return until Christ comes again. So Israel was primarily peoples of the tribe of Judah, many of Levi, and many of Benjamin and Simeon.
Jesus did send His Apostles (Jews) to the lost sheep of Israel and perhaps His Father had already made known to these tribes of His birth - thinking Wise Men (Magi). Josephus notes a large mass of people beyond count, living not too far away from Israel and called them the lost 10 tribes. Some scholars say these were the Parthian Empire - ruling people at time of His life. They also believe the Magi came from this Empire.
i'm pretty sure they all had something to do before Jesus asked them to be his disciples.
They immediately followed Him.
The disciples immediately followed Jesus because they believed he was the Messiah and wanted to learn from him and spread his teachings.
He did. There were women, such as Mary Magdalene, who followed or supported Jesus.
And Jesus got up and followed him (Jairus), with his disciples. (Matthew 9:19)
Jesus.
the disciples followed Jesus and did what Jesus said. Jesus picked his disciples. The disciples were ordinary people. Jesus doesn't only like the people who are rich and successfully. he loves us all equally, no matter who we are or what we look like, he made us all and saw that we were good
These were called both disciples and apostles.
Jesus' disciples
Before his baptism, Jesus did not have formally identified disciples. The Gospels suggest that he began to gather followers after his baptism by John the Baptist, when he started his public ministry. However, there were individuals, such as John the Baptist's own disciples, who recognized Jesus' significance before his baptism. The formal calling of his disciples, as recorded in the Gospels, occurs after this event.
his disciples, before Jesus ascended into heaven
Disciples, also known as the Apostles, were the small group of men that followed Jesus Christ before His death on the cross.
