Revelation 6:9-11 - The Fifth Seal
9 When the Lamb broke the fifth seal, I saw at the foot of the altar the souls of those whose lives had been sacrificed because of the word of God and of the testimony which they had given. 10 And now in loud voices they cried out, saying, "How long, O Sovereign Lord, the holy One and the true, dost Thou delay judgment and the taking of vengeance upon the inhabitants of the earth for our blood?" 11 And there was given to each of them a long white robe, and they were bidden to wait patiently for a short time longer, until the full number of their fellow bondservants should also complete--namely of their brethren who were soon to be killed just as they had been.
