2 He seized the dragon-that old serpent, who is the devil, Satan-and bound him in chains for a thousand years. 3 The angel threw him into the bottomless pit, which he then shut and locked so Satan could not deceive the nations anymore until the thousand years were finished. Afterward he must be released for a little while.
Matthew Henry's Commentary on Revelation 20:2-3
Commentary on Revelation 20:1-3
(Read Revelation 20:1-3)
Here is a vision, showing by a figure the restraints laid on Satan himself. Christ, with Almighty power, will keep the devil from deceiving mankind as he has hitherto done. He never wants power and instruments to break the power of Satan. Christ shuts by his power, and seals by his authority. The church shall have a time of peace and prosperity, but all her trials are not yet over.
