'The Twelve' in the Bible

These are the names of the twelve apostles: first, Simon, who was called Peter, and his brother Andrew, and James the son of Zebedee and his brother John,

Jesus said to them, "In the new world, I tell you, when the Son of Man takes his seat on his glorious throne, you who have followed me will also sit upon twelve thrones, and judge the twelve tribes of Israel!

When Jesus was about to go up to Jerusalem, he took the Twelve off by themselves, and said to them as they were on the way,

Then one of the Twelve, named Judas Iscariot, went to the high priests,

When evening came, he took his place at table with the twelve disciples.

Just as he was speaking, Judas, one of the Twelve, came up, and with him a great crowd with swords and clubs, from the high priests and the elders of the people.
