'Bar sabbas' in the Bible

Then they nominated two men, Joseph called Barsabbas, who was also called Justus, and Matthias.

Then the apostles and elders in cooperation with the whole church passed a resolution to select and send some men of their number with Paul and Barnabas to Antioch. These were Judas, who was called Barsabbas, and Silas, leading men among the brothers.
