Charles Ellicott Commentary Exodus 28:43

"And they shall be upon Aaron, and upon his sons, when they go in unto the tent of meeting, 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 unto his seed after him." — Exodus 28:43 (ASV)

The tabernacle of the congregation. —Heb., the tent of meeting.

The holy place seems to be here the court of the tabernacle, within which the altar was to be set up (Exodus 40:6; Exodus 40:29).

That they bear not iniquity, and die. —The death penalty is threatened against the sin of ministering without the garments needed for decency, as against the sin of neglecting to wear the robe of the ephod (Exodus 28:35). In both cases a Divine vengeance, rather than a legal punishment, is probably intended.
