Exodus 28:40

“And for Aaron’s sons thou shalt make coats, etc.] Of fine linen, of woven work, as in (<023927>Exodus 39:27), these were different from the broidered coat of the high priest, and the blue robe of the ephod: and thou shall make for them girdles; linen ones, to gird up their linen coats, which were long, that they might the more expeditiously perform their service; and which is an instruction to all the priests of the Lord, true believers in Christ, to be ready, forward, and diligent in the work of the Lord; and especially to ministers of the word, who, as their doctrines and lives ought to be pure, signified by the priest’s linen garment, so they should be girt about with the girdle of truth,…”

“(Compare Exodus 39:1-31.) Moses is now commanded to commit all that pertains to the offerings made to the Lord in the sanctuary to the exclusive charge of the members of a single family, who were to hold their office from generation to generation.
