Midrash for Leviticus 8:28

29) (Vayikra 8:27) ("and he waved them as a wave offering before the L–rd."): We are hereby taught (the procedure for) the waving of the offerings. (Vayikra 8:28): "And Moses took them from their hands": We are hereby taught how he takes the meal-offering from the hands of the sotah and waves it.

30) (Vayikra 8:28): "They are a miluim (investiture) offering for a sweet savor": We are hereby taught that the miluim offering is called "a sweet savor." And does this not follow a fortiori, viz.: If a king of flesh and blood who acquires a lover makes a festival for him, the King of kings, the Holy One Blessed be He, who invests a Cohein for Himself, how much more so!
