What does Acts 1:19 mean?
In the middle of Peter's account of Judas' death, Luke adds details for Theophilus (Acts 1:1). First, he more fully describes what happened to Judas. While Matthew merely mentioned Judas hanged himself (Matthew 27:3–10), Luke adds that Judas' corpse fell and the impact burst open his gut, spilling out his intestines (Acts 1:18). Now, Luke includes the Greek name of the field, which the Jews in Jerusalem would have known by the Aramaic.It's unclear what Judas thought was going to happen when he betrayed Jesus to the chief priests and elders of the Sanhedrin, the ruling Jewish council. He received his payment, thirty pieces of silver, ahead of time (Matthew 26:14–16), and waited for a dark, quiet moment when he knew where Jesus would not be surrounded by a crowd. The Sanhedrin had intended to wait until after the week-long Feast of Unleavened Bread, which directly followed the Passover. They knew that Jesus had many followers, or at least fans, in Jerusalem who could riot (Matthew 26:3–5).
But they were not as in control of the situation as they thought. At the Last Supper, Jesus directed Judas, now possessed by Satan, to start the process (John 13:27). Late that night, Judas gathered guards and servants of the chief priests and elders and took them to the Mount of Olives where he knew Jesus and the disciples would be relatively removed from the crowds (Luke 21:37).
This was all according to Judas' plan…at first. We don't know what changed Judas' perspective. After Judas realized that Pilate had sentenced Jesus to death, Judas was horrified. We don't know if he thought Jesus would "just" be beaten. Perhaps Judas expected Jesus to once again escape as He had done before (Luke 4:28–30; John 8:59; 10:39). Perhaps Satan, who had possessed him at the Last Supper, finally left, leaving Judas' mind clearer. Some interpreters suggest Judas thought the arrest would force Jesus to take up arms against His enemies.
Whatever happened in Judas' mind and heart, he tried to return the silver, but was denied. While he hanged himself, the chief priests used the money to buy a field and called it Akeldama. Somewhat fittingly, they used it for a cemetery.
