Numbers 35:27 BBE

²⁵  And let the people keep the man responsible for the death safe from the hands of him who has the right of punishment for blood, and send him back to his safe town where he had gone in flight: there let him be till the death of the high priest who was marked with the holy oil.

²⁶  But if ever he goes outside the walls of the safe town where he had gone in flight,

²⁷  And the giver of punishment, meeting him outside the walls of the town, puts him to death, he will not be responsible for his blood:

²⁸  Because he had been ordered to keep inside the safe town till the death of the high priest: but after the death of the high priest the taker of life may come back to the place of his heritage.

²⁹  These rules are to be your guide in judging through all your generations wherever you may be living.
