Ulangan 19:12

19:12 The elders of his own city must send for him and remove him from there to deliver him over to the blood avenger ¹  to die.

[19:12]  ¹ tn The גֹאֵל הַדָּם (go’el haddam, “avenger of blood”) would ordinarily be a member of the victim’s family who, after due process of law, was invited to initiate the process of execution (cf. Num 35:16-28). See R. Hubbard, NIDOTTE 1:789-94.
