Now when Festus was come into the province,.... Of Judea, which was a Roman province, over which he was made governor by Nero, the Roman emperor, in the room of Felix; he now being landed in some part of the province, namely, at Caesarea, and so might be said to have entered upon the government of it, as the phrase will bear to be rendered; after three days he ascended from Caesarea to Jerusalem; he very likely came by sea from Italy to Judea, and landed at Caesarea; for though Joppa was the nearest port to Jerusalem, yet Caesarea was the safest, and most commodious port, being made so by Herod; See Gill on Act 18:22, and besides, it seems to have been very much the residence of the kings and governors of Judea, Act 12:19 here Festus stayed three days after his landing, to rest himself after the fatigue of the voyage, and then went up to Jerusalem, the metropolis of the province of Judea.
