Revelation 6:10 → Genesis 4:10

The martyrs under the altar cry, "How long, O Lord, holy and true, until You avenge our blood and judge those who dwell upon the earth?" (Rev 6:10), echoing the first murdered righteous one, whose blood "cries out to Me from the ground" (Gen 4:10). From Abel onward, innocent blood has a voice before God, appealing for justice; John shows that the slain saints of every age share Abel's cry and that God hears it. This connection runs along the Voice of Blood longitudinal theme — shed righteous blood as a perpetual plea for divine vindication — with an analogy between Abel, the first righteous victim, and the company of all the martyrs, whose cry is Abel's cry continuing rather than a heightened version of it. The movement is one of number and time: from one righteous victim to the full number of the slain, whose blood is heard and answered in God's appointed hour (Rev 6:11). Typology is withheld here, and Hebrews 12:24 shows why: the blood of Jesus "speaks a better word than the blood of Abel," for it cries not for vengeance but for mercy and atonement. The telos is the assurance that the Judge who is "holy and true" will perfectly vindicate His people, while the gospel itself flows from blood that pleads pardon — so that Christ is seen as both the righteous avenger and the Lamb whose blood reconciles.
