Acts 21:20-23

When they heard this, they praised God. Then they said to Paul: “You see, brother, how many thousands of Jews have believed, and all of them are zealous for the law. They have been informed that you teach all the Jews who live among the Gentiles to turn away from Moses, telling them not to circumcise their children or live according to our customs. What shall we do? They will certainly hear that you have come, so do what we tell you. There are four men with us who have made a vow.
