Luke 22:1-6

The Festival of Unleavened Bread, which is also called Passover, was approaching. The leading priests and teachers of religious law were plotting how to kill Jesus, but they were afraid of the people’s reaction.

Then Satan entered into Judas Iscariot, who was one of the twelve disciples, and he went to the leading priests and captains of the Temple guard to discuss the best way to betray Jesus to them.  They were delighted, and they promised to give him money. So he agreed and began looking for an opportunity to betray Jesus so they could arrest him when the crowds weren’t around.

Matthew 26:14-16

Then Judas Iscariot, one of the twelve disciples, went to the leading priests and asked, “How much will you pay me to betray Jesus to you?” And they gave him thirty pieces of silver. From that time on, Judas began looking for an opportunity to betray Jesus.
