3 Bible Verses about Angels, Important Events

This is he that was in the church in the wilderness, with the Angel who spake to him in mount Sinai, and with our fathers; who received the living oracles to give to us:

And I saw an angel descending out of heaven, having the key of the bottomless pit, and a great chain in his hand. And he laid hold on the dragon, the old serpent, who is the devil and Satan, and bound him a thousand years, And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he might deceive the nations no more, till the thousand years should be fulfilled. After this he must be loosed for a small time.

For the Lord himself shall descend from heaven, with a shout, with the voice of an archangel, and with the trumpet of God; and the dead in Christ shall rise first.
