Revelation 10:5-7

New King James Version

⁵ The angel whom I saw standing on the sea and on the land ^(A)raised up his ^[a]hand to heaven ⁶ and swore by Him who lives forever and ever, ^(B)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, ^(C)that there should be delay no longer, ⁷ but ^(D)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.
