A Bedouin horseman riding along a desert track, seeing the sign
of blood on the side of the road, will instantly dismount and
cover it with earth “to lay the _mâred_” (the avenger of
blood). The idea is that the spirit of him who died by an act of
violence, the victim of man’s hate, the _mâred_, calls for
vengeance on him who has taken the life of his fellow man.--“The
Witness of the Wilderness.”
