Between blood and blood; of which See Poole on "Deuteronomy 17:8". Between law and commandment, statutes and judgments; when any debates or differences shall arise about the meaning of any of God's laws, one party possibly putting this, and the other a quite differing sense upon the same place, or one alleging one place, and the offer another place, which may seem to clash with it. Ye shall even warn them that they trespass not against the Lord; ye shall not only give a righteous sentence for what is past, but ye shall admonish the offender, and others, to take better heed to themselves and their ways for the future. This do, and ye shall not trespass; so you shall not bring guilt and wrath upon yourselves and others, which otherwise you will certainly do.
