Rambam: Maaseh Hakarbanot, Chapter 1

Re: I think you may be misreading the words of the Sifsei Chachamim. His intention is to explain the seeming difficulty in the verse, which says "It is consecrated to the Kohen", in the singular tense, although it is referring to both the loaf, the wafer, and the foreleg. He therefore explains, that the word "it" is to be read in context of the word "And he shall wave", meaning that whatever was included in the wave - The loaf, the wafer, and the foreleg - are all consecrated to the Kohen.
The words he uses "B'Koach Maamar" do not mean that it was with the power of speech (levitation) that they were waved, rather it means that this word is using the power of the earlier mentioned word, "He shall wave", and is therefore referring to all three items. Reply
