Acts 11:25

BARNABAS, FINDING THE WORK IN ANTIOCH TOO MUCH FOR HIM, GOES TO TARSUS FOR SAUL--THEY LABOR THERE TOGETHER FOR A WHOLE YEAR WITH MUCH SUCCESS, AND ANTIOCH BECOMES THE HONORED BIRTHPLACE OF THE TERM CHRISTIAN. (Act 11:25-26) Then departed Barnabas to Tarsus for to seek Saul--Of course, this was after the hasty despatch of Saul to Tarsus, no doubt by Barnabas himself among others, to escape the fury of the Jews at Jerusalem. And as Barnabas was the first to take the converted persecutor by the hand and procure his recognition as a disciple by the brethren at Jerusalem (Act 9:27), so he alone seems at that early period to have discerned in him those peculiar endowments by virtue of which he was afterwards to eclipse all others. Accordingly, instead of returning to Jerusalem, to which, no doubt, he sent accounts of his proceedings from time to time, finding that the mine in Antioch was rich in promise and required an additional and powerful hand to work, he leaves it for a time, takes a journey to Tarsus, "finds Saul" (seemingly implying--not that he lay hid [BENGEL], but that he was engaged at the time in some preaching circuit--see on Act 15:23), and returns with him to Antioch. Nor were his hopes disappointed.
