Leviticus 23:11

והניף AND HE SHALL WAVE [THE OMER] — Every form of the root נוף used in connection with sacrifices signifies that one moves the latter about both horizontally (מוליך ומביא) and upwards and downwards (מעלה ומוריד); he moves it about horizontally to prevent (i. e. the act was symbolical of preventing) destructive winds, he moves it about upwards and downwards to keep away injurious dews (cf. Rashi on Exodus 29:24) (Menachot 62a). לרצנכם TO BE ACCEPTED FOR YOU — If you offer it according to this precept it shall effect favourable acceptance for you. ממחרת השבת ON THE MORROW AFTER THE DAY OF REST [THE PRIEST SHALL WAVE IT] — This must mean on the morrow of the first day of the Passover festival (on the 16th of Nisan); for if you say that it means on the morrow of the weekly Sabbath (i. e. on a Sunday) you do not know which particular Sabbath Scripture is referring to (Menachot 66a).

and he shall wave the ῾omer before the Lord, to be accepted for you: on the morrow after the sabbath the priest shall wave it.
