TSK · Numbers 31:29

You are to sanctify the breast of the wave offering and the thigh of the contribution, which were waved and lifted up as a contribution from the ram of consecration, from what belongs to Aaron and to his sons.

Thus you are to offer up a raised offering to the LORD of all your tithes which you receive from the Israelites; and you must give the LORD’s raised offering from it to Aaron the priest.

Be careful not to overlook the Levites as long as you live in the land.
