Amplified Bible, Classic Edition

9 Then the fifth angel blew [his] trumpet, and I saw a star that had fallen from the sky to the earth; and to the angel was given the key ^[a]of the shaft of the Abyss (the bottomless pit).

² He opened the ^[b]long shaft of the Abyss (the bottomless pit), and smoke like the smoke of a huge furnace puffed out of the ^[c]long shaft, so that the sun and the atmosphere were darkened by the smoke from the long shaft.^(A)
