1 Corinthians 7:18

But He said to them, “Not all men can accept this statement, but only those to whom it has been given.

Some men came down from Judea and began teaching the brothers, “Unless you are circumcised according to the custom of Moses, you cannot be saved.”

But some of the sect of the Pharisees who had believed stood up, saying, “It is necessary to circumcise them and to command them to keep the Law of Moses.”

and they have been told about you, that you are teaching all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children nor to walk according to the customs.
