On repeated missionary tours, the apostle Paul carried on a zealous ministry also among the people who lived in the area to which Peter later sent the first Biblical letter bearing his name. — Acts 18: 23; 19: 10; Galatians 1: 1, 2.
Korduvate misjonireiside ajal teenis apostel Paulus innukalt ka nende inimeste hulgas, kes elasid paikkonnas, kuhu Peetrus saatis hiljem esimese piiblilise kirja, mis kannab tema nime.
