Deuteronomy 19:6; Deuteronomy 19:12

Deuteronomy 19:6

6 Lest the avenger of the blood pursue the slayer, while his heart is hot, and overtake him, because the way is long, and slay him; whereas he was not worthy of death, inasmuch as he hated him not in time past.

Deuteronomy 19:12

12 Then the elders of his city shall send and fetch him thence, and deliver him into the hand of the avenger of blood, that he may die.
