Deuteronomy 19:5

Matthew(i) 5 If he smyte his neyghboure ignorantly & hated him not in tyme passed: As when a man goeth vnto the wood wyth hys neyghbour to hewe wood, & as his hand fetcheth a stroke wt the axe, the head slippeth from the helue & smyteth his neyghboure that he dyeth: the same shal flee vnto one of the same cities & be saued.
