Luke 22
Judas agrees to betray Jesus
Now the feast of unleavened bread drew nigh, which is called the Passover. And the chief priests and scribes sought how they might kill him; for they feared the people.
Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve. And he went his way, and communed with the chief priests and captains, how he might betray him unto them. And they were glad, and covenanted to give him money. And he promised, and sought opportunity to betray him unto them in the absence of the multitude.
As Passover approaches, the chief priests and scribes look for a way to kill Jesus without provoking the people. Satan enters Judas Iscariot, one of the Twelve, who goes to the chief priests and the temple officers and agrees, for money, to hand Jesus over to them when no crowd is present.
What does this mean?
"Captains" (KJV) or "officers" were commanders of the temple guard, which kept order in the temple precincts. The meaning of "Iscariot" is uncertain; suggestions include "man from Kerioth," a town, and a word for "assassin."
Historical context
Passover, recalling the exodus from Egypt, was followed at once by the seven-day Feast of Unleavened Bread (Leviticus 23:5–6), and in popular usage the names were interchangeable, as here. The festival swelled Jerusalem's population, and the Roman governor brought troops to the city, so the authorities feared a riot.
Why does it matter?
Satan's entry into Judas recalls the devil's departure "for a season" after the temptation (4:13); John's Gospel uses similar language (John 13:27). Luke does not say how much money was offered; Matthew names thirty pieces of silver (Matthew 26:15).
