Joshua 20:3-6

MSTC(i) 3 that the slayer that killeth any person unawares and unwittingly, may flee thither. And those cities shall be your refuge from the avenger of blood. 4 And the slayer shall flee unto one of those Cities and shall stand in the entering of the gate of the city and shall show his cause in the ears of the elders of the said city. And they shall take him into the city unto them, and shall give him a place that he may dwell among them. 5 And when the avenger of blood followeth after him they shall not deliver the slayer unto his hand: because he smote his friend ignorantly, and hated him not before time. 6 And he shall dwell in the said city until he stand before the congregation in judgment, and until the death of the high priest that shall be in those days. And then shall the slayer return and come unto his own city and unto his own house, and unto the city from whence he fled.'"
