Malachi 2:6

“The law of truth was in his mouth, etc.] The Gospel, the word and doctrine of truth; which comes from the God of truth; is concerning Christ the truth and men are guided into it by the Spirit of truth; it contains most glorious truths, and nothing but truth: and this was in the mouth of Christ, being put there by his Father, who gave him what he should say, and what he should speak; and which was preached by him in the most faithful manner, and so as it never was by any other, for which he was abundantly qualified: and iniquity was not found in his lips; there was none in his nature; nor in his heart; nor in his life; nor in his lips; none could be found there by men nor devils: there was no…”

“law of truth was in his mouth--He taught the people the truths of the law in all its fulness (Deu 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 (Deu 17:8-9; Deu 19:17). walked with me--by faith and obedience (Gen 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; Jam 3:18). turn may . . . from iniquity--both by positive precept and by tacit example "walking with God" (Jer 23:22; Dan 12:3; Jam 5:20).”

“The law of truth was in his mouth - Apart from those cases, which were brought to the priests at the tabernacle (Deuteronomy 17:9-11; Deuteronomy 19:17 (add Deuteronomy 21:5; Ezekiel 44:23-24), hence, the use of אלהים Exodus 21:6; Exodus 22:7-8.), in which their voice was the voice of God through them, to teach the law was part of the office both of the priest and Levite. Of the priest God says; Leviticus 10:11, “that ye may teach the children of Israel all the statutes, which the Lord hath spoken unto them by the hand of Moses:” of the tribe of Levi generally Moses says Deuteronomy 33:10, “They shall teach Jacob Thy judgments and Israel Thy law.” After the schism of the ten tribes, a…”

“Was in his mouth - He taught to the people. Aaron, Eleazar, Phineas, every one of those priests or Levites, in what age soever they lived; who feared God, and were humble. Iniquity is not found - He judged not with respect of persons, or for bribes. He walked - His whole life was a continual walking with God; he lived with God, and to him. In peace - With God, and it was his aim to live peaceably with others. Malachi 2:7”
