'Betraying' in the Bible

And Judas, the one who was betraying him, answered [and] said, "{Surely I am not he, am I}, Rabbi?" He said to him, "You have said [it]."

Get up, let us go! Behold, the one who is betraying me is approaching!"

Now the one who was betraying him had given them a sign, saying, "[The one] whom I kiss--he is [the one]. Arrest him!"

saying, "I have sinned [by] betraying innocent blood!" But they said, "What [is that] to us? You see to [it]!"
