Gevurot 15:35-37

Orthodox Jewish Bible

³⁵ And Rav Sha’ul and Bar-Nabba were staying in Syrian Antioch saying shiurim and drashot with also many others, the content of these being the dvar Hashem.

³⁶ And after some yamim Rav Sha’ul said to Bar-Nabba, "Let’s return, then, and visit the Achim b’Moshiach throughout every city in which we proclaimed the dvar Hashem to see how they are doing."

³⁷ And Bar-Nabba was deciding to take along also Yochanan called Markos.
