John Chrysostom

For it says, "When the brethren were aware of this, they brought him down to Caesarea, and sent him forth to Tarsus," at the same time to preach, and likely to be more in safety, as being in his own country. But observe, I pray you, how far it is from being the case that everything is done by miraculous grace; how, on the contrary, God does in many things leave them to manage for themselves by their own wisdom and in a human way; so to cut off the excuse of idle people: for if it was so in the case of Paul, much more in theirs.

"To Caesarea, and sent him forth to Tarsus:" so that, I suppose, he did not continue his journey by land, but sailed the rest of it. And this departure is Providentially ordered, that he might preach there also: and so likewise were the plots against him ordered by God's Providence, and his coming to Jerusalem, that the story about him might no longer be disbelieved.
