Acts 1:21-23

21“Therefore, from among the men who have accompanied us during the whole time the Lord Jesus went in and out among us —

22beginning from the baptism of John until the day he was taken up from us — from among these, it is necessary that one become a witness with us of his resurrection.”

23So they proposed two: Joseph, called Barsabbas, who was also known as Justus, and Matthias.
