blood money

The now commonly-used German term Blutgeld (literally “blood money”), which today is primarily used to refer to an atonement payment by a murderer as compensation to the victim’s next of kin or for a reward for reporting a murderer or criminal, was made popular in 1522 in the German New Testament translation by Martin Luther.
