[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.

[19:17]  ² tn The appositional construction (“before the Lord, that is, before the priests and judges”) indicates that these human agents represented the Lord himself, that is, they stood in his place (cf. Deut 16:18-20; 17:8-9).
