In the nine days of waiting between Jesus’s ascension and the day of Pentecost, the disciples remained together in prayer. During this time, Peter reminded them that the death of Judas had left the fellowship of the Twelve with a vacancy. Two men were nominated, Joseph called Barsabbas, who was surnamed Justus, and Matthias. After prayer, the disciples cast lots, and Matthias was chosen to join them. And with that, Matthias disappears from recorded history.
