And as they spake unto the people, the priests, and the captain of the temple, and the Sadducees, came upon them, The priests - These persons had evidenced the most implacable enmity against Christ from the beginning.
The captain of the temple - See this office particularly explained in the note on Luke 22:4 (note).
The Sadducees - Whose whole system was now in danger by the preaching of the resurrection of Christ; for they believed not in the immortality of the soul, nor in any future world. These made a common cause with the priests, etc., to suppress the evidence of Christ's resurrection, and silence the apostles.
