Aquila and Priscilla in the Bible

Acts 18:1-3 After these things Paul departed from Athens, and came to Corinth; 2 And found a certain Jew named Aquila, born in Pontus, lately come from Italy, with his wife Priscilla; (because that Claudius had commanded all Jews to depart from Rome:) and came unto them. 3 And because he was of the same craft, he abode with them, and wrought: for by their occupation they were tentmakers.
Acts 18:18-19 And Paul after this tarried there yet a good while, and then took his leave of the brethren, and sailed thence into Syria, and with him Priscilla and Aquila; having shorn his head in Cenchrea: for he had a vow. 19 And he came to Ephesus, and left them there: but he himself entered into the synagogue, and reasoned with the Jews.
Acts 18:26 And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly.

Romans 16:3-4 Greet Priscilla and Aquila my helpers in Christ Jesus: 4 Who have for my life laid down their own necks: unto whom not only I give thanks, but also all the churches of the Gentiles.
