Hilchos Maasei Hakarbanos 9:8

The things to be waved are placed on the owner’s hands with the fats directly on his hands and the breast and thigh on them. The kidneys and the lobe of the liver are placed on top of those. If the offering has bread, it is placed on top and all these things are then waved.

Hilchos Maasei Hakarbanos 9:9

In the case of a nazir’s ram, the kohein removes the parts that are to be burned, puts aside the breast and thigh, and cooks the rest of the ram in the women’s courtyard. He takes the cooked foreleg of the ram and one of every ten breads brought with it, along with the breast, the thigh and the parts to be burned, and puts all this on the nazir’s hands. He puts his hands under the owner’s hands and waves everything in the manner detailed.
