Did Paul always name names?

Acts 17:10 And the brethren immediately sent away Paul and Silas by night unto Berea: who coming thither went into the synagogue of the Jews. 11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. 12 Therefore many of them believed; also of honourable women which were Greeks, and of men, not a few. 13 But when the Jews of Thessalonica had knowledge that the word of God was preached of Paul at Berea, they came thither also, and stirred up the people.
