Leviticus 8:13

And Moses brought Aaron's sons
His four sons, Nadab and Abihu, Eleazar and Ithamar, to the door of the tabernacle of the congregation; he ordered and directed them to come there, or sent proper persons to fetch them, or from one part of the court, where they were, he might accompany them thither:

and put coats upon them, and girded them with girdles:
which were made of fine linen, ( Exodus 39:27 Exodus 39:28 ) and the coats being made long to reach down to the ankles, needed girdles, especially when in service, that they might perform it more expeditiously:

and put bonnets on them;
which were made of fine linen also, and differed from the mitre of the high priest only in the manner of rolling up the linen:

as the Lord commanded Moses;
as all the above things were made, so they were all put on, according to the directions Moses received of the Lord, who was faithful in his house, with respect to everything he enjoined him, ( Hebrews 3:2 Hebrews 3:5 ) .
