John Wesley on Acts 4:2

The priests being grieved - That the name of Jesus was preached to the people; especially they were offended at the doctrine of his resurrection; for as they had put him to death, his rising again proved him to be the Just One, and so brought his blood upon their heads. The priests were grieved, lest their office and temple services should decline, and Christianity take root, through the preaching of the apostles, and their power of working miracles: the captain of the temple - Being concerned to prevent all sedition and disorder, the Sadducees - Being displeased at the overturning of all their doctrines, particularly with regard to the resurrection.
