Deuteronomy 19:6

“Otherwise, the avenger of blood might pursue the manslayer in a rage, overtake him if the distance is great, and strike him dead though he did not deserve to die, since he did not intend any harm.”

“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.”

“lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and smite him mortally; whereas he was not worthy of death, inasmuch as he hated him not in time past.”

“lest the redeemer of blood pursue after the man-slayer when his heart is hot, and hath overtaken him (because the way is great), and hath smitten him--the life, and he hath no sentence of death, for he is not hating him heretofore;”
