Charles Ellicott Commentary Acts 11:1

"Now the apostles and the brethren that were in Judaea heard that the Gentiles also had received the word of God." — Acts 11:1 (ASV)

And the apostles and brethren that were in Judæa . . .—The context implies that the news travelled, while Peter remained at Cæsarea, first probably to Joppa and Lydda, and afterwards to Jerusalem.
