English: “And he shall wave them” — this teaches that they require a single joint waving. If he waved each separately he has still fulfilled the obligation; one might think he must wave and wave again, therefore it says “a wave offering” (singular) and not “wave offerings.”
Joint tenufah
Chazal teach that the asham lamb and the log of oil are waved together as one tenufah; separate wavings also suffice, but repeated sets of waving are not required.
