One man should die for the people

Then Satan entered Judas, surnamed Iscariot, who was numbered among the twelve. So he went his way and conferred with the chief priests and captains, how he might betray Him to them.

And they were glad, and agreed to give him money. So he promised and sought opportunity to betray Him to them in the absence of the multitude.
