4. And you shall know that I have sent this commandment unto you, that my covenant might be with Levi,
5. My covenant was with him of life and peace; and I gave them to him for the fear with which he feared me, and was afraid before my name.
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.
7. For the priest's lips should preserve knowledge, and they should seek the law from his mouth: for he is the messenger of the LORD of hosts.
