Revelation 6:10-11
Revelation 6:10-11 NCV
These souls shouted in a loud voice, “Holy and true Lord, how long until you judge the people of the earth and punish them for killing us?” Then each one of them was given a white robe and was told to wait a short time longer. There were still some of their fellow servants and brothers and sisters in the service of Christ who must be killed as they were. They had to wait until all of this was finished.
