Acts 4:2

Being sore troubled because they taught the people, and proclaimed in Jesus the resurrection from the dead.

Being sorely troubled ... The word thus rendered occurs only here and in Acts 16:18; and this is an inadequate translation. Alexander Campbell translated it "indignant,"[5] far more accurately describing the attitude of the priests. And indeed they must have been indignant. Sure enough, Christ was risen from the dead; and that eventuality foreseen by them (Matthew 27:65) in which "the last error was worse than the first" had truly come to pass. Moreover, the great popularity of the gospel message threatened their political base, promised to hold them up before the people as murderers, as ignoramuses concerning the Holy Scriptures, and as deserving of universal contempt. To proud, arrogant men like themselves, the situation had become intolerable; and their venomous hatred overflowed against the apostles.
