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?

People's New Testament

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.

Wesley's Notes

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.

Jamieson-Fausset-Brown Bible Commentary

10. How long-Greek, "Until when?" As in the parable the woman (symbol of the Church) cries day and night to the unjust judge for justice against her adversary who is always oppressing her (compare below, Re 12:10); so the elect (not only on earth, but under Christ's covering, and in His presence in Paradise) cry day and night to God, who will assuredly, in His own time, avenge His and their cause, "though He bear long with them." These passages need not be restricted to some particular martyrdoms, but have been, and are receiving, and shall receive partial fulfilments, until their last exhaustive fulfilment before Christ's coming. So as to the other events foretold here. The glory even of those in Paradise will only be complete when Christ's and the Church's foes are cast out, and the earth will become Christ's kingdom at His coming to raise the sleeping saints.

Lord-Greek, "Master"; implying that He has them and their foes and all His creatures as absolutely at His disposal, as a master has his slaves; hence, in Re 6:11, "fellow servants," or fellow slaves follows.

holy-Greek, "the Holy one."

avenge-"exact vengeance for our blood."

on-Greek, "from them."

that dwell on the earth-the ungodly, of earth, earthly, as distinguished from the Church, whose home and heart are even now in heavenly places.

Matthew Henry's Concise Commentary

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.
