'Shed' in the Bible

They cried out in a loud voice, "Holy and true Sovereign, how long will it be before you judge and take revenge on those living on the earth who shed our blood?"

For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy.

because his judgments [are] true and righteous, because he has passed judgment on the great prostitute who corrupted the earth with her sexual immorality, and has avenged the blood of his slaves {shed by} her hand!"
