John Wesley on Numbers 35:26

He shall abide in it - Be confined to it, partly to shew the hatefulness of murder in God's account by so severe a punishment, inflicted upon the very appearance of it, and partly for the security of the man - slayer, lest the presence of such a person, and his conversation among the kindred of the deceased, might occasion reproach and blood - shed. The death of the high - priest - Perhaps to shew that the death of Christ (the true High - priest, whom the others represented) is the only means whereby sins are pardoned and sinners set at liberty.
