Numbers 35:9-29
King James Version (KJV)

9 And the Lord spake unto Moses,
saying,

10 Speak unto the children of
Israel, and say unto them, When ye be come over Jordan into the land of Canaan;

11 Then ye shall appoint you
cities to be cities of refuge for you; that the slayer may flee thither, which killeth any person at
unawares.

12 And they shall be unto you
cities for refuge from the avenger; that the manslayer die not, until he stand before the
congregation in judgment.
