Malachi 2:6

The law of truth; the law of God which is the truth, the doctrine of the law according to the true meaning thereof. Was in his mouth; he did teach it to the people, he resolved all cases by this law; Aaron, Eleazar, Phinehas, or, as we must understand it, every one of those godly priests or Levites, in what age soever they lived, who, as Zechariah 2:5, feared God, and were humble. They taught the people (as was their duty) first to know the law of God, and then to obey it; this by their example, the other by their instruction. The law of truth was in his mouth, he pronounced according to the law truly, pronouncing that unclean which the law determined unclean, and that clean which was clean. Iniquity was not found in his lips; he judged not with respect to persons, nor for bribes perverted judgment, nor judged that lawful which was unlawful, or that unlawful which was lawful. He walked with me; his whole life was a continual walking with God, as Enoch's was, and Noah's was, and as God required Abraham's should be, in holy fear of his majesty, in true love of his precepts, and reverent observing his ordinances; he lived with God, and to him. In peace, with God, and with men; it was his aim to live peaceably towards others, that God might make them peaceable toward him, and God gave him much of that he desired. And equity; in rectitude of mind, or in sincerity and uprightness, free from hypocrisy; or else in all righteousness among men. And did turn many away from iniquity; by his instructions, and by his excellent example, he converted many from ways of sin.
