Jesus chose 12 people to follow him. Who were these guys?

Bonus Questions
What did Jesus do the night before he chose the 12 apostles? (Luke 6:12-13)
Who was the first apostle Jesus called? Where did that calling take place? (Compare Matthew 4:18–22, Mark 1:16-20 and Luke 5:1–11 with John 1:35–51)
What is the difference between an apostle and a disciple? (Consider Luke 9:1-6 and Luke 10:1-7)

Main Thought
There’s not a lot written about these guys. But, some of them had some cool nicknames. Whatever you think about who was called, when, where, and why, the number 12 seems important.
