그들의 지을 옷은 이러하니 곧 흉패와 에봇과 겉옷과 반포 속옷과 관과 띠라 그들이 네 형 아론과 그 아들들을 위하여 거룩한 옷을 지어 아론으로 내게 제사장 직분을 행하게 할지며
Mishneh Torah, Vessels of the Sanctuary and Those Who Serve Therein
The golden garments are the garments of the High Priest, and they are eight garments: The four of an ordinary priest, 5) the cloak, 6) the ephod, 7) the breastplate, and 8) the forehead plate. The sash of the High Priest was embroidered and was made in a similar manner as that of the ordinary priest. [Similarly,] the hat [that the Torah mentions] with regard to Aaron corresponds to the hat mentioned with regard to his sons. [The difference is that] the hat of the High Priest is worn like fabric swathed around a hernia (turban), and the hat of an ordinary priest is worn like an ordinary hat. Therefore, it is called 'migba'at.'
Sefer HaChinukh
The commandment of wearing the priestly clothes: That the priests were commanded to wear special clothes for aggrandizement and glory — and then they may serve in the Temple — as it is stated (Exodus 28:4), “and they shall make priestly clothes for Aharon your brother and his sons.”
