Then the congregation shall judge between the slayer and the revenger of blood according to these judgments:
Numbers 35:12
and the cities have been to you for a refuge from the redeemer, and the man-slayer doth not die till his standing before the company for judgment.
Joshua 20:6
and he hath dwelt in that city till his standing before the company for judgment, till the death of the chief priest who is in those days -- then doth the man-slayer turn back and hath come unto his city, and unto his house, unto the city whence he fled.'
