Priscilla and Aquila net Apostle Paul while he was in Corinth. This instance is mentioned in Acts 18:1–28. They were from the city of Rome, but they had to come to Corinth since The Roman Emperor Claudius banished all the Jewish people from Rome. Priscilla and Aquila were tentmakers just like Paul. We believe they met thanks to their common business. Priscilla and his wife Aquila were originally Jewish, and they converted into Christianity after meeting Apostle Paul.
Apostle Paul, Priscilla and Aquila spent more than a year in Corinth. Eventually they left for Ephesus all together. They spent a year and a half in Ephesus then Paul had to leave Ephesus after the Riot of Silversmiths. Priscilla and Aquila remained in Ephesus and went on preaching.
It is told in Acts 18:24–26, A preacher named Apollos came to Ephesus. Aquila and her husband took Apollos into their house and thought him scriptures, turned him into a complete Christian.
The last reference we see in the Holy Bible about Priscilla and Aquila is in the letter of Apostle Paul to Timothy
”Greet Prisca and Aquila, and the household of Onesiphorus.”2 Timothy 4:19
