“Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them.”
King James Version (KJV)
15:12 Miracles and wonders - By which also what St. Peter had said was confirmed.
Ac 15:12 All the multitude kept silence. After Peter's reminder of his work among the Gentiles, Paul and Barnabas were probably called on to show whether their work, like Peter's, showed that God was with them. They therefore gave some account of the miracles that God had wrought by their hands, thereby attesting the Divine favor.
