Psalm 7:13

For after all it is only just for God to repay with affliction those who afflict you,

they cried out with a loud voice, "O Sovereign Lord, holy and true, how long before you judge and avenge our blood on those who dwell on the earth?"

for they shed the blood of saints and prophets, and you have given them blood to drink. They deserve it."
