Gevurot 15:37-39

Orthodox Jewish Bible

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

³⁸ But Rav Sha’ul was insisting not to take along this one, the one having withdrawn from them from Pamphylia, not having gone with them to the avodas kodesh ministry of the Moshiach’s Shlichus.

³⁹ And there was a sharp disagreement so that they were separated from one another, and Bar-Nabba took Markos and sailed away to Cyprus.
