'Bar sabbas' in the Bible

So they brought forward two men, Joseph called Bar-Sabbas (surnamed Justus) and Matthias;

Then the apostles and the presbyters, together with the whole church, decided to select some of their number and send them with Paul and Barnabas to Antioch. The men selected were Judas (called Bar-Sabbas) and Silas, prominent members of the brotherhood.
