Rashi
For a priest’s lips It is incumbent upon them to guard knowledge. Why? Because... teaching should be sought from his mouth This matter has already (Deut. 33:10) been delivered to them. “They shall teach Your judgments to Jacob.”
Rashi
for he is a messenger the agent of the Holy One, blessed be He; like the ministering angels, to serve Him and to enter into His compartment. [I.e., into the place where God’s presence is manifest.]
Tze'enah Ure'enah
“The lips of a priest will guard, etc.” [2:7]. It was bestowed on them to know understanding and wisdom because Torah is desired from them. That is, the priests were commanded in the Torah that they should show and teach Torah to Israel. He is compared to an angel who served the Holy One. The priest also serves the Holy One in the inner sanctum of the Temple where another person has no authority to go.17Rashi, Malachi, 2:7.
