'Betrayer' in the Bible

Then Judas, His betrayer, replied, “Surely not I, Rabbi?”“You have said it,” He told him.

Get up; let’s go! See, My betrayer is near.”

His betrayer had given them a sign: “The One I kiss, He’s the One; arrest Him!”

Then Judas, His betrayer, seeing that He had been condemned, was full of remorse and returned the 30 pieces of silver to the chief priests and elders.
