Deuteronomy 19:4-6

Rotherham(i) 4 And, this, is the case of the manslayer, who shall flee thither and live,––Whoso shall smite his neighbour unwittingly, he, not having hated him aforetime; 5 as when one entereth with his neighbour into a forest, to fell trees, and his hand fetcheth a stroke with the axe, to cut down the tree, and the head flieth off from the handle, and lighteth upon his neighbour, that he die, he, shall flee into one of these cities, and live; 6 lest the blood redeemer pursue the manslayer, because his heart is hot, and overtake him, because the way is long, and he smite him so as to take away his life,––he not being worthy of death, seeing that he had not been hating him, aforetime.
