⁶ and swore by Him who lives forever and ever, ^(A)who created heaven and the things that are in it, the earth and the things that are in it, and the sea and the things that are in it, ^(B)that there should be delay no longer, ⁷ but ^(C)in the days of the sounding of the seventh angel, when he is about to sound, the mystery of God would be finished, as He declared to His servants the prophets.
