Acts 11:18 - Ellicott's Commentary On The Whole Bible

They held their peace, and glorified God. — The difference of tenses in the two Greek verbs implies that they first held their peace, and then began a continuous utterance of praise. The fact was obviously one of immense importance in its bearing on the question at issue between St. Paul and the Judaisers, of which St. Luke had seen so much and which he sought, by his narrative, to settle. Not only had the first step in the free admission of the Gentiles been taken by the chief of the Apostles, and under direct guidance from above, but it had received the formal approval of the Apostles and other members of the Church of the Circumcision at Jerusalem. The Judaisers, in opposing St. Paul, were acting against the Church from which they pretended to derive their authority.
