12 Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a Sabbath day’s journey. 13 And when they had entered, they went up into the upper room where they were staying: Peter, James, John, and Andrew; Philip and Thomas; Bartholomew and Matthew; James the son of Alphaeus and Simon the Zealot; and Judas the sonof James.  

25 to take part in this ministry and apostleship from which Judas by transgression fell, that he might go to his own place.” 26 And they cast their lots, and the lot fell on Matthias. And he was numbered with the eleven apostles.
