Resurrection, the first
'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

2
He opened the pit of the abyss, and smoke went up out of the pit, like the smoke from a burning furnace. The sun and the air were darkened because of the smoke from the pit.
