Leviticus 22:2 commands respect for sacred offerings, directly setting up the specific penalty in 22:3 for approaching them while unclean.

Leviticus 7:20 also threatens being cut off for eating sacrifices while unclean, reinforcing the same principle of uncleanness leading to exclusion.

Leviticus 7:21 extends the cut-off consequence to touching unclean then eating sacrifices, parallel to Leviticus 22:3's rule on approaching holy things.

Leviticus 6:18 defines who may eat most holy offerings, reinforcing the boundary that 22:3 enforces with the penalty for approaching unclean.

Numbers 18:11 permits only the ceremonially clean to eat the offerings, aligning directly with 22:3's prohibition against the unclean approaching them.

Numbers 19:13 imposes being cut off for uncleanness from touching a dead body, a parallel penalty to 22:3's for approaching offerings unclean.

2 Chronicles 30:19 shows Hezekiah interceding for those who ate the Passover while unclean, contrasting with 22:3's strict penalty of being cut off.

Ezra 2:63 restricts eating most holy food until priestly status is verified, a different restriction than 22:3's uncleanness but both protect sanctity.
