Deuteronomy 19:4-5 ▼

4 And this is the case of the manslayer, that shall flee thither and live: whoso killeth his neighbour unawares, and hated him not in time past;

5 as when a man goeth into the forest with his neighbour to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the head slippeth from the helve, and lighteth upon his neighbour, that he die; he shall flee unto one of these cities and live;
