'The Twelve' in the Bible

Now the names of the twelve apostles were: First, Simon, also called Peter, Andrew, his brother, James and John, sons of Zebedee,

Jesus said to them, "Truly I tell you, [since] you have become my followers, in the time of new beginnings [i.e., the church age], when the Son of man sits on His glorious throne, you apostles will also sit on twelve thrones, judging [i.e., through their writings] the twelve tribes of Israel [i.e., God's people].

As Jesus was going up to Jerusalem He took the twelve apostles aside. As they traveled along He said to them,

As they [i.e., the twelve apostles and Jesus] were leaving Jericho [Note: This was a town about eighteen miles northeast of Jerusalem], a huge crowd followed them.

And when they [i.e., Jesus and the twelve apostles] approached Jerusalem and came close to Bethphage, near the Mount of Olives [Note: This was about three-fourths of a mile east of Jerusalem], Jesus sent two disciples on ahead,

Then one of the twelve apostles, named Judas Iscariot, went to the leading priests

And while He was still speaking, Judas, one of the twelve apostles, came with a large crowd who were carrying swords and clubs. They had come from the leading priests and elders of the [Jewish] people.
