“In the same quarters were possessions of the chief man of the island, whose name was Publius; who received us, and lodged us three days courteously.”
King James Version (KJV)
28:7 The chief man of the island - In wealth if not in power also. Three days - The first three days of our stay on the island.
Ac 28:7 The chief man of the island. His name, Publius, is Roman, and he was doubtless the Roman governor of the island. It would be simply his duty to take care of the Roman officer Julius and his company. Hence, he "lodged them courteously" for three days until they could provide for themselves.
