Hebrews explicitly recalls bodies of sin sacrifices whose blood is brought into the holy place being burned outside the camp; Leviticus 16:27 is one of the clearest Torah examples.

Hebrews develops the Day of Atonement into a major Christological contrast: repeated annual priestly action is set beside Christ’s once-for-all self-offering and heavenly appearance. Leviticus 16 provides the ritual world of atonement, cleansing, priestly entry, blood, and removal of sin that Hebrews reinterprets around Jesus.

Leviticus 16 requires the high priest to make atonement for himself as well as for the people during the Day of Atonement. Hebrews contrasts such priests, who must repeatedly offer and who share human weakness, with Jesus, the fitting high priest whose self-offering is once for all. The contrast uses the Levitical priesthood as real background without reducing every priestly offering to Leviticus 16 alone.
