Deuteronomy 19:4-6

CKJV_Strongs(i)
  4 H1697 And this is the case H7523 of the slayer, H5127 which shall flee H2425 there, that he may live: H5221 Whoever kills H7453 his neighbor H1097 ignorantly, H8130 whom he hated H8543 not in time H8032 past;
  5 H935 As when a man goes H3293 into the wood H7453 with his neighbor H2404 to hew H6086 wood, H3027 and his hand H5080 fetches a stroke H1631 with the axe H3772 to cut down H6086 the tree, H1270 and the head H5394 slips H6086 from the handle, H4672 and lights H7453 upon his neighbor, H4191 that he die; H5127 he shall flee H259 unto one H5892 of those cities, H2425 and live:
  6 H1350 Lest the avenger H1818 of the blood H7291 pursue H310 the slayer, H3588 while H3824 his heart H3179 is hot, H5381 and overtake H1870 him, because the way H7235 is long, H5221 and kill H5315 him; H4941 whereas he was not worthy H4194 of death, H3588 inasmuch as H8130 he hated H8543 him not in time H8032 past.
