The Greek word abussos is used seven time in Revelation, and that makes one wonder if they correspond to the days of creation. SOme do pretty well.
Day 1: A star falls from heaven with a key to the abyss (9:1). the world is de-lightened.
Day 2: From the abyss comes a cloud that snuffs the sun; it is an anti-firmament through which no light can pass (9:2).
Day 3: The locusts have a king, who is the angel of the abyss (9:11). The name is given in both Hebrew and Greek; there is a “land name” for the king, and a “sea name.”
Day 4: This is the height of the power of the abyss, when teh beast from the abyss overcomes and kills the two witnesses (11:7).
Day 5: The beast that ascends out of the abyss returns to destruction (17:8).
Day 6: An angel from heaven chains the dragon in the abyss (20:1), perhaps a type of new Adam who defeats the serpent.
Day 7: Sabbath comes for the world and the nations because the dragon is chained in the abyss for a thousand years (20:3).
