Revelation 9:1-2

Expanded Bible

9 Then the fifth angel blew his trumpet, and I saw a star fall from ·the sky [or heaven] to the earth. The star was given the key to the ·deep hole [shaft] ·that leads to the bottomless pit [^Lof the Abyss; ^Cthe place of the dead and/or a prison for fallen angels; Luke 8:31; Rom. 10:7]. ² Then ·it [or he] opened up the ·hole that leads to the bottomless pit [shaft of the Abyss], and smoke came up from the ·hole [shaft] like smoke from a ·big [great; giant] furnace. Then the sun and ·sky [air] became dark because of the smoke from the ·hole [shaft].
