Leviticus 7:11-38 details the peace offering law, specifying the priestly portions from these sacrifices — the same perpetual due mentioned here.

Leviticus 7:14 also assigns a portion of peace offerings to the priest who throws the blood — reinforcing the same principle.

Leviticus 7:32-34 repeats the same perpetual statute: the breast and right shoulder from peace offerings belong to the priests — exactly the portions sanctified in Exodus 29:28.

Leviticus 7:34 restates this same law — the breast and thigh from peace offerings are a perpetual due for Aaron and his sons.

Leviticus 10:15 reiterates the same perpetual statute for the heave shoulder and wave breast, confirming what Exodus 29:28 established.

Numbers 18:29 instructs Levites to present a contribution from their tithe to the priests — directly connected to how priests receive their portion.

Leviticus 9:21 shows Aaron waving the breast and thigh from the peace offering — a specific instance of the priestly portions prescribed here.

Numbers 5:9 states that all contributions of holy things given to the priest become his — reinforcing the principle of priestly due from offerings.

Numbers 15:21 commands a contribution from the first of dough — a different offering type, but also a perpetual due to the LORD (and later to priests).

Numbers 18:24 assigns the tithe as a contribution to the Levites — a different offering but a similar perpetual due for the tribe.

Numbers 31:29 describes a contribution from war spoils given to the priest — a different source but same concept of priestly due.
