(a) The events that led to the election of Matthias as one of the twelve are: After the Ascension, Peter assumed leadership of the brethren. He reminded them of the need to maintain their master's original number of twelve. He quoted David in the Psalms to support his suggestion. Since the place of Judas Iscariot in the ministry had become vacant, there was the need to replace him. The person to replace him must be somebody who had witnessed with Jesus from the time of His baptism to His death and resurrection. Joseph Barsabas and Matthias who fitted the description were nominated for the post. The congregation prayed to God to assist in making the choice. After the prayer, they cast lots for them and the lot fell on Matthias. Matthias was then enrolled as one of the twelve to replace Judas.
