Prisca, also called Priscilla (Greek: Πρίσκιλλα), was a wife of Aquila. Aquila was from Pontus.
After Emperor Claudius of the Romans expelled all Jews, including Priscilla and Aquila, from Italy, the couple went to Corinth. Paul met and stayed with them there due to their shared tent-making craft.
After this Paul left Athens and went to Corinth. There he met a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife, Priscilla, because [the Roman Emperor] Claudius had issued an edict that all the Jews were to leave Rome. Paul went to see them, and because he was of the same trade, he stayed with them; and they worked together for they were tent-makers.— Acts 18:1–18:2 (AMP)
Other believers in God, such as Titius Justus and Crispus, also resided in Corinth. God commanded Paul to continue preaching in Corinth and told Paul that he would be safe and that many of God's people were in the city.
One night the Lord said to Paul in a vision,Do not be afraid anymore, but go on speaking and do not be silent; for I am with you, and no one will attack you in order to hurt you, because I have many people in this city.— Acts 18:9–18:10 (AMP)
Paul remained and preached in Corinth for sixteen months and then went to Ephesus. Priscilla and Aquila accompanied Paul to Ephesus. Paul remained in Ephesus for same time and then left.
An Alexandrian Jew named Apollos went to Ephesus. Apollos knew the Scriptures and the baptism of John the Baptist. Apollos spoke at the synagogue. Priscilla and Aquila listened to Apollos and then taught Apollos more about the way of God. Apollos become a great help to the early Church. He went to Achaia and preached and defended Christianity in debates with Jews.
[…] But when Priscilla and Aquila heard him [Apollos], they took him aside and explained more accurately to him the way of God [and the full story of the life of Christ]. And when Apollos wanted to go across to Achaia (southern Greece), the brothers encouraged him and wrote to the disciples, [urging them] to welcome him gladly. When he arrived, he was a great help to those who, through grace, had believed and had followed Jesus as Lord and Savior, for he powerfully refuted the Jews in public discussions, proving by the Scriptures that Jesus is the Christ (the Messiah, the Anointed).— Acts 18:26–18:28 (AMP)
In his letter to the Christians of Rome, Paul mentioned how Priscilla and Aquila risked their lives for Paul and asked the Romans to greet them.
Greet Prisca and Aquila, my fellow workers in Christ Jesus, who risked their own necks [endangering their very lives] for my life. To them not only do I give thanks, but also all the churches of the Gentiles. Also greet the church that meets in their house.— Romans 16:3–16:5 (AMP)
In a letter to the Christians of Corinth, Paul greeted the Corinthians on the behalf of Priscilla, Aquila, and the church that met in their house.
The churches of Asia send you their greetings. Aquila and Prisca, together with the church [that meets] in their house, send you their warm greetings in the Lord. All the believers greet you. Greet one another with a holy kiss.— 1 Corinthians 16:19–16:20 (AMP)
In a letter to Timothy, Paul asked Timothy to greet Priscilla, Aquila, and the household of Onesiphorus for him (2 Timothy 4:19 (AMP)).
