Malachi 2:7
Rahlfs Septuagint (1935) · Berean Standard Bible
ὅτι χείλη ἱερέως φυλάξεται γνῶσιν καὶ νόμον ἐκζητήσουσιν ἐκ στόματος αὐτοῦ διότι ἄγγελος κυρίου παντοκράτορός ἐστιν
For the lips of a priest should preserve knowledge, and people should seek instruction from his mouth, because he is the messenger of the LORD of Hosts.
