Leviticus 10:6 commands priests not to mourn in a way that defiles — directly parallel to avoiding uncleanness from the dead.

Leviticus 10:7 restricts priests from leaving the sanctuary during mourning, reinforcing the principle of priestly separation from death.

Leviticus 22:4 refers to uncleanness from contact with the dead as one barrier to priests eating holy offerings — same impurity system.

Ezekiel 44:25 reiterates the same rule for priests: not to defile themselves for the dead, with exceptions only for close relatives.

Numbers 6:7 places the same prohibition on Nazirites — no contact with dead even for close relatives — paralleling priests' holiness requirements.

Numbers 19:11 details the seven-day uncleanness from touching a corpse, grounding the priestly restriction here in general defilement law.

Numbers 19:14 gives the general impurity law for a dead body in a tent, which underlies the priestly restriction in Leviticus 21:1.

Numbers 19:16 expands uncleanness from touching dead bodies or graves — the same impurity priests must avoid per Leviticus 21:1.

Numbers 5:2 commands uncleanness from the dead to be removed from the camp — a general rule applying to all, contrasting with priests' stricter rule.
