Exodus 29:27
And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, even of that which is for Aaron, and of that which is for his sons:

Exodus 29:24 describes the wave offering ritual itself — placing the items in Aaron's hands and waving them, which leads to the consecration in verse 27.
Exodus 29:28 immediately extends the same rule: the breast and shoulder from the ordination ram become a perpetual priestly portion from all Israel's peace offerings.
