  11 H376 But if any man H8130 [H8802] shall hate H7453 his neighbour, H693 [H8804] and lie in wait H6965 [H8804] for him, and rise up H5221 [H8689] against him, and smite H5315 him mortally H4191 [H8804] that he dieth, H5127 [H8804] and he shall flee H259 into one H411 of these H5892 cities:
  12 H2205 Then the elders H5892 of his city H7971 [H8804] shall send H3947 [H8804] and bring H5414 [H8804] him from there, and give H3027 him into the hand H1350 [H8802] of the avenger H1818 of blood, H4191 [H8804] that he may die.
  13 H5869 Thine eye H2347 [H8799] shall not pity H1197 [H8765] him, but thou shall remove H5355 the guilt of innocent H1818 blood H3478 from Israel, H2895 [H8804] that it may be well with thee.
