Final answer:
The replacement for Judas Iscariot was Matthias, chosen among the apostles through prayer and casting lots.
Step-by-step explanation:
The Replacement for Judas Iscariot
After the betrayal of Jesus by Judas Iscariot, the remaining apostles felt the need to appoint a replacement to maintain the symbolic representation of the twelve tribes of Israel. According to the Gospels, the chosen disciple was Matthias.
Scriptural Basis
The selection of Matthias is described in the Book of Acts (1:15-26). The apostles decided to choose a replacement for Judas and narrowed down the list to two candidates, Matthias and Joseph Barsabbas. Through a process of prayer and casting lots, Matthias was ultimately chosen to take Judas' place among the apostles.
