Are there 12 apostles? Are there 70 apostles?
When I was growing up and learning about Jesus, I found that he had 12 apostles. I was looking at a page about Mark the Evangelist recently and it says that he was one of 70 disciples. On that same page about the about 70 disciples there is a picture titled "Icon of the Seventy Apostles.".
Are there 12 or 70? Are the 12 somehow separate from the 70 or are they part of the same group?
Is there anything in the Bible I can read that deals with this?
