3 and threw him into the pit, and locked and sealed it over him, so that he would deceive the nations no more, until the thousand years were ended. After that he must be let out for a little while.

Matthew Henry's Commentary on Revelation 20:3

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.
