The work of Angels

Minister before God

Revelation 8:2 

And I saw the seven angels who stand before God, and to them were given seven trumpets.

Revelation 14:15-19 

15 Then another angel came out of the temple and called in a loud voice to him who was sitting on the cloud, “Take your sickle and reap, because the time to reap has come, for the harvest of the earth is ripe.”

16  So he who was seated on the cloud swung his sickle over the earth, and the earth was harvested.

17  Another angel came out of the temple in heaven, and he too had a sharp sickle.

18  Still another angel, who had charge of the fire, came from the altar and called in a loud voice to him who had the sharp sickle, “Take your sharp sickle and gather the clusters of grapes from the earth's vine, because its grapes are ripe.”

19  The angel swung his sickle on the earth, gathered its grapes and threw them into the great winepress of God's wrath.

Guard the abyss

Revelation 9:1 

The fifth angel sounded his trumpet, and I saw a star that had fallen from the sky to the earth. The star was given the key to the shaft of the Abyss.

Revelation 20:1-3 

1 And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain.

2  He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years.

3  He threw him into the Abyss, and locked and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended. After that, he must be set free for a short time.
