Berean Standard Bible
And when the Lamb opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony they had upheld.
Context
7And when the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” 8Then I looked and saw a pale green horse. Its rider’s name was Death, and Hades followed close behind. And they were given authority over a fourth of the earth, to kill by sword, by famine, by plague, and by the beasts of the earth. 9And when the Lamb opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony they had upheld. 10And they cried out in a loud voice, “How long, O Lord, holy and true, until You avenge our blood and judge those who dwell upon the earth?” 11Then each of them was given a white robe and told to rest a little while longer, until the full number of their fellow servants, their brothers, were killed, just as they had been killed.
