“And in these days came prophets from Jerusalem unto Antioch.”
King James Version (KJV)
11:26 And the disciples were first called Christians at Antioch - Here it was that they first received this standing appellation. They were before termed Nazarenes and Galileans.
11:28 Agabus rising up - In the congregation. All the world - The word frequently signifies all the Roman empire. And so it is doubtless to be taken here.
11:29 Then - Understanding the distress they would otherwise be in on that account, the disciples determined to send relief to the brethren in Judea - Who herein received a manifest proof of the reality of their conversion.
Ac 11:27 In these days. While Saul was at Antioch. Came prophets. See PNT "Ac 2:17".
