Acts 1:16-17; Acts 1:20-22
"Brothers, it was necessary for the Scriptures to be fulfilled concerning Judas, who guided the Temple police to arrest Jesus. This was predicted long ago by the Holy Spirit, speaking through King David.
Judas was one of us, chosen to share in the ministry with us."
Peter continued, "This was predicted in the book of Psalms, where it says, 'Let his home become desolate, with no one living in it.' And again, 'Let his position be given to someone else.' "
"So now we must choose another man to take Judas's place. It must be someone who has been with us all the time that we were with the Lord Jesus --
from the time he was baptized by John until the day he was taken from us into heaven. Whoever is chosen will join us as a witness of Jesus' resurrection."
