JUSTUS jus’ təs (̓Ιοῦστος, G2688; Lat. Justus, just or righteous). A name common among Jews and proselytes, usually combined with some other Jewish name.

1. Surname of Joseph Barsabbas, one of the two men put forward to take the place of Judas in the apostolic band (Acts 1:23). Papias relates that he survived a heathen plot by drinking deadly poison without injury (Euseb. Hist. III. 39). See Barsabas.

2. Titius Justus, “a worshiper of God,” at Corinth who, after the closing of the Jewish synagogue, opened his home next door to Paul’s preaching (Acts 18:7). The form of his name varies in the MSS, Titus Justus, Titius Justus, or only Justus (KJV). That he was the Titus of Paul’s epistles is an ancient but unfounded guess. Some would identify him with Gaius of Corinth (Rom 16:23). See Gaius 3.

3. Jesus Justus, Paul’s appreciated Jewish co-worker who sent greetings to the church in Colossae (Col 4:11).
