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.
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.
6:9-11 The sight the apostle beheld at the opening the fifth seal was very affecting. He saw the souls of the martyrs under the altar; at the foot of the altar in heaven, at the feet of Christ. Persecutors can only kill the body; after that there is no more they can do; the soul lives. God has provided a good place in the better world, for those who are faithful unto death. It is not their own death, but the sacrifice of Christ, that gives them entrance into heaven. The cause in which they suffered, was for the word of God; the best any man can lay down his life for; faith in God's word, and the unshaken confession of that faith. They commit their cause to Him to whom vengeance belongs. The Lord is the comforter of his afflicted servants, and precious is their blood in his sight. As the measure of the sin of persecutors is filling up, so is the number of the persecuted, martyred servants of Christ. When this is fulfilled, God will send tribulation to those who trouble them, and unbroken happiness and rest to those that are troubled.
