Adam Clarke, on Acts 13:5

“And when they were come to Salamina, they preached the word of God in the synagogues of the Jews. And they had John also in the ministry.”

“Salamis - The capital of the island of Cyprus; afterwards called Constantia, and now Salina, situated on the eastern part of the island. They preached the word of God - Τον λογον, The doctrine of God, the Christian religion, emphatically so called. They had also John to their minister - This was John Mark, of whom we heard, Act 12:25; for their minister, ὑπηρετην, to assist them in minor offices, as deacon or servant, that they might give themselves wholly to the doctrine of the Lord.”
