malachi 2:6 The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity. - Free Bible Online

      6. law of truth was in his mouth--He taught the people the truths of the law in all its fulness (De 33:10). The priest was the ordinary expounder of the law; the prophets were so only on special occasions.
      iniquity . . . not found--no injustice in his judicial functions (De 17:8, 9; 19:17).
      walked with me--by faith and obedience (Ge 5:22).
      in peace--namely, the "peace" which was the fruit of obeying the covenant (Mal 2:5). Peace with God, man, and one's own conscience, is the result of "walking with God" (compare Job 22:21; Isa 27:5; Jas 3:18).
      turn may . . . from iniquity--both by positive precept and by tacit example "walking with God" (Jer 23:22; Da 12:3; Jas 5:20).
