  3 H7523 [H8802] That the slayer H5221 [H8688] that killeth H5315 any person H7684 unintentionally H1847 and unknowingly H5127 [H8800] may flee H4733 there: and they shall be your refuge H1350 [H8802] from the avenger H1818 of blood.
  4 H5127 [H8804] And when he that doth flee H259 to one H5892 of those cities H5975 [H8804] shall stand H6607 at the entrance H8179 of the gate H5892 of the city H1696 [H8765] , and shall declare H1697 his cause H241 in the ears H2205 of the elders H5892 of that city H622 [H8804] , they shall take H5892 him into the city H5414 [H8804] to them, and give H4725 him a place H3427 [H8804] , that he may dwell among them.
  5 H1350 [H8802] And if the avenger H1818 of blood H7291 H310 [H8799] shall pursue H5462 [H8686] him, then they shall not deliver H7523 [H8802] the slayer H3027 into his hand H5221 [H8689] ; because he smote H7453 his neighbour H1097 H1847 unknowingly H8130 [H8802] , and had not hated H8543 H8032 him in times past.
