Acts 18:2-3, 18, 26

And he found a certain Jew named Aquila, born in Pontus, who had recently come from Italy with his wife Priscilla (because Claudius had commanded all the Jews to depart from Rome); and he came to them. So, because he was of the same trade, he stayed with them and worked; for by occupation they were tentmakers.

So Paul still remained a good while. Then he took leave of the brethren and sailed for Syria, and Priscilla and Aquila were with him. He had his hair cut off at Cenchrea, for he had taken a vow.

So he began to speak boldly in the synagogue. When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately.
