The officer in charge of the temple guards is the same term used in 4.1 They wondered what had happened to the apostles is one possible meaning of the difficult Greek expression in this verse. An American Translation* (“they were very much at a loss as to what would come of it”) and Jerusalem Bible (“they wondered what this could mean”) are two other possible translations of this somewhat puzzling expression.
