Acts 15:12
The whole assembly became silent as they listened to Barnabas and Paul telling about the signs and wonders God had done among the Gentiles through them — the silence (siopao, to be quiet) suggests Peter's words commanded assent, with Barnabas and Paul's testimony providing empirical corroboration. The reiteration of signs and wonders as evidence of God's work parallels Peter's argument: divine action, not human argument, settles the matter.
