According to Luke, Satan had entered Judas prior to the Last Supper:
a Now the feast of Unleavened Bread, called the Passover,* was drawing near,
b and the chief priests and the scribes were seeking a way to put him to death, for they were afraid of the people.
c Then Satan entered into Judas,* the one surnamed Iscariot, who was counted among the Twelve,d
and he went to the chief priests and temple guards to discuss a plan for handing him over to them.
They were pleased and agreed to pay him money.
He accepted their offer and sought a favorable opportunity to hand him over to them in the absence of a crowd.
Preparations for the Passover.e
When the day of the Feast of Unleavened Bread arrived, the day for sacrificing the Passover lamb,–Luke 22: 1-7
(I sure do wish the CAFs Bible BB code still worked. )
And according to John, it occurred at the Last Supper:
After he took the morsel, Satan entered him. So Jesus said to him, “What you are going to do, do quickly.”–John 13: 27
How do we reconcile these 2 passages?
