In Leviticus 8:12, the anointing oil poured on Aaron's head is the very oil that consecrates him, grounding why he must not leave the tent.

Leviticus 8:30 also uses the anointing oil to consecrate Aaron and his sons, linking directly to the reason they must stay inside the tent.

Leviticus 21:12 parallels this exactly: the high priest must not leave the sanctuary because the anointing oil of God is upon him.

Leviticus 21:10 describes the high priest on whom the anointing oil was poured—the same oil that requires staying in the tent.

Exodus 28:41 commands anointing Aaron's sons to consecrate them—the same anointing that requires them to remain in the tent here.

Exodus 30:30 directly commands anointing Aaron and his sons, providing the basis for their obligation to stay in the sanctuary.

Exodus 40:13-15 establishes the perpetual priesthood through anointing—the same consecration that keeps them from leaving the tent.

Exodus 29:7 is the direct command to pour anointing oil on Aaron's head—the same oil that marks him as holy and confines him here.
