Barabbas was a choice Pilate gave the Jews instead of Jesus. But did you know that Barabbas' first name was also Jesus? This detail isn't mentioned in the King James on, but is in the New Revised Standard Version. While it's an interesting coincidence that Barabbas's first name was Jesus, wait till you hear the rest. First, here's the entire story, as compiled from the gospels.
  Now at the festival the governor was accustomed to release a prisoner for the people, anyone whom they wanted.
At that time they had a notorious prisoner, called Jesus Barabbas.(Who was in prisoon for certain sedition and for murder.)
So when they had gathered, Pilate said to them, 
Whom will you that I release to you, Jesus Barabbas or Jesus who is called Messiah? 
For he knew that it was out of envy that they had delivered him
When he was sitting on the judgment seat, his wife sent to him, 
Have nothing to do with that just man, for  I have suffered a great deal today in a dream about him. 
But the chief priests and the elders persuaded the crowd to ask for Barabbas and to kill Jesus
The governor said unto them, 
Which of the two do you want me to release unto you? And they said, Barabbas. 
And hesaid to them, 
Then what shall I do with Jesus who is called Messiah? They all said unto him, Let him be crucified! 
Then he asked, 
Why, what evil has he done? But they shouted all the more, Let him be crucified!
Not only was Barabbas's first name Jesus, but his last name, Barabbas, meansson (bar) of the father (abba). Jesus had always referred to himself as the Son of the Father (and his adversaries had always refused to acknowledge that he was). So now we had two men named Jesus, each a "son of the father", but opposite fathers, it would seem. Jesus was an innocent man about to murdered, and Barabbas was a murderer about to be set free.
