John Gill Commentary Acts 15:35

"But Paul and Barnabas tarried in Antioch, teaching and preaching the word of the Lord, with many others also." — Acts 15:35 (ASV)

Paul also and Barnabas continued in Antioch
As well as Silas: teaching and preaching the word of the Lord; the Gospel of Christ; not the word of men, but the word of the Lord, of which he is both the author and subject: this they preached in season, and out of season, with power, purity, plainness, and faithfulness.

And many others also ;
who either came along with them from Jerusalem, when they brought the letter from thence, or were here before; who came hither upon the persecution raised at the death of Stephen, (Acts 11:19Acts 11:20) or they were the prophets which afterwards came from Jerusalem thither, (Acts 11:27) such as Simeon called Niger, Lucius of Cyrene, and Manaen, (Acts 13:1) .
