Numbers 35:26-29 Webster Bible Translation (WBT)

26. But if the slayer shall at any time come without the border of the city of his refuge, whither he had fled;

27. And the avenger of blood find him without the borders of the city of his refuge, and the avenger of blood shall kill the slayer; he shall not be guilty of blood:

28. Because he should have remained in the city of his refuge until the death of the high priest: but after the death of the high priest the slayer shall return into the land of his possession.

29. So these things shall be for a statute of judgment to you throughout your generations in all your dwellings.
