11. Second of the "better promises" (Heb 8:6).
      they shall not--"they shall not have to teach" [ALFORD].
      his neighbour--So Vulgate reads; but the oldest manuscripts have "his (fellow) citizen."
      brother--a closer and more endearing relation than fellow citizen.
      from the least to the greatest--Greek, "from the little one to the great one." Zec 12:8, "He that is feeble among them shall be as David." Under the old covenant, the priest's lips were to keep knowledge, and at his mouth the people were to seek the law: under the new covenant, the Holy Spirit teaches every believer. Not that the mutual teaching of brethren is excluded while the covenant is being promulgated; but when once the Holy Spirit shall have fully taught all the remission of their sins and inward sanctification, then there shall be no further' need of man teaching his fellow man. Compare 1Th 4:9; 5:1, an earnest of that perfect state to come. On the way to that perfect state every man should teach his neighbor. "The teaching is not hard and forced, because grace renders all teachable; for it is not the ministry of the letter, but of the spirit (2Co 3:6). The believer's firmness does not depend on the authority of human teachers. God Himself teaches" [BENGEL]. The New Testament is shorter than the Old Testament, because, instead of the details of an outward letter law, it gives the all-embracing principles of the spiritual law written on the conscience, leading one to spontaneous instinctive obedience in outward details. None save the Lord can teach effectually, "know the Lord."
