They shall be upon Aaron and upon his sons— They, that is, all the sacerdotal vestments as above described, shall, on pain of death, be worn always during the time of their ministrations; but at no other time, and in no other place. See Ezekiel 42:14; Ezekiel 44:19. Hence some account for St. Paul's not knowing the high-priests, Acts 23:5 as he was not clothed in his sacerdotal vestments. It shall be a statute for ever, means as long as the Jewish policy and priesthood shall subsist.

43 And they shall be upon Aaron, and upon his sons, when they come in unto the tabernacle of the congregation, or when they come near unto the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever unto him and his seed after him.
