'Interpreters' in the Bible

Now at this time some prophets came down from Jerusalem to Antioch.

Now in the church at Antioch there were prophets [who spoke a new message of God to the people] and teachers: Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen who had been brought up with Herod [Antipas] the tetrarch, and Saul.

Judas and Silas, who were themselves prophets (divinely inspired spokesmen), encouraged and strengthened the believers with many words.
