“And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?”
King James Version (KJV)
6:10 And they cried - This cry did not begin now, but under the first Roman persecution. The Romans themselves had already avenged the martyrs slain by the Jews on that whole nation. How long - They knew their blood would be avenged; but not immediately, as is now shown them. O Lord - The Greek word properly signifies the master of a family: it is therefore beautifully used by these, who are peculiarly of the household of God. Thou Holy One and true - Both the holiness and truth of God require him to execute judgment and vengeance. Dost thou not judge and avenge our blood? - There is no impure affection in heaven: therefore, this desire of theirs is pure and suitable to the will of God. The martyrs are concerned for the praise of their Master, of his holiness and truth: and the praise is given him, #Rev 19:2|, where the prayer of the martyrs is changed into a thanksgiving: Thou holy One and true: True and right are thy judgments. How long dost thou not judge and avenge our blood? He hath judged the great whore, and hath avenged the blood of his servants.
Re 6:10 And they cried with a loud voice. Their cry denotes that the church had suffered long and severely, and they raise a cry for deliverance.
