But Paul was not at all in favor of taking someone who had left them and refused to continue on in the work [of preaching the Gospel] when they were in Pamphylia. [See 13:13].
Then another person said [to Jesus], “Lord, I will become your follower, but first let me say goodbye to my family.” [Note: There was the likelihood that family members might try to dissuade him from his commitment to follow the Lord].
Now Paul and his companions sailed from Paphos and arrived at Perga [a town in the province] of Pamphylia. [It was here that] John Mark left the party [of evangelists and attendants] and returned to [his home in] Jerusalem. [See 12:12].
