The Betrayal Study

I think it's safe to say nearly everyone knows the story of Judas Iscariot; believers and non-believers alike. The name Judas has become synonymous with the word betrayal. As I studied out these short scriptures I ran across a very interesting point in the Old Scofield Study Bible that I had never considered before. So we have Judas arriving with all the guards and their arrangement is that whomever Judas kisses is the one the guards are to arrest, which will of course be Jesus. So in verse 49 Judas kisses Jesus and calls Him Master. Now let's look closely at verse 50. I'll be honest, I think I've always just read right through this verse, but Jesus calls Judas "friend" as He asks Judas where he's come from. The study note I mentioned points out that the word friend here is from the Greek word, Hetaire, which more accurately translates to comrade. The commentary draws from this that Jesus was using an endearing term even as Judas betrayed Him, and concludes that this means the Lord does not disown Judas. There is another commentary I've read that takes it a step further and suggests that verse 50 is there to show that at that moment Jesus was offering Judas one last chance to repent. I don't know if that is true and the scriptures do not confirm or deny such a possibility, but I will admit it does sound like something our Lord would do. What do you think?
