Revelation 6:9-11

Living Bible

⁹ And when he broke open the fifth seal, I saw an altar, and underneath it all the souls of those who had been martyred for preaching the Word of God and for being faithful in their witnessing. ¹⁰ They called loudly to the Lord and said, “O Sovereign Lord, holy and true, how long will it be before you judge the people of the earth for what they’ve done to us? When will you avenge our blood against those living on the earth?” ¹¹ White robes were given to each of them, and they were told to rest a little longer until their other brothers, fellow servants of Jesus, had been martyred on the earth and joined them.
