Why does the Torah record the waving of the Chazos and the Shok ha'Yamin only after the burning of the Chalavim in the previous Pasuk?
1.
Ha'amek Davar: Not having yet 1 been informed by Moshe to perform the Tenufah on the Shok, Aharon did not perform it until after the Chalavim had been burned. In fact, the ox and the ram were waved and brought on the Mizbe'ach independently together with their respective calves; whereas for some reason, the two Chazos, which Aharon only waved together with the Shok after the Chalavim were burned, were waved and burned simultaneously. 2
