Joshua 20:4-6

ECB(i) 4 And when one flees to one of those cities and stands at the portal of the portal of the city and words his word in the ears of the elders of that city, they gather him into the city to themselves and give him a place to settle among them. 5 And when the redeemer of blood pursues after him, they shut not the murderer into his hand - because he smote his friend unknowingly and hated him not three yesters ago: 6 and he settles in that city until he stands at the face of the witness for judgment until the death of the great priest being in those days: then the murderer returns and comes to his own city and to his own house to the city whence he fled.
