What are the connotations of "Chazeh ha'Tenufah" and "Shok ha'Terumah"?
Rashi (in Sh'mos 29:24): The two terms combined incorporate waving in all four directions and up and down. 1
Oznayim la'Torah: Refer to 7:32:3:2. The Torah refers to the Chazeh as 'Chazeh ha'Tenufah', because, since it is a gift from the portion of Hashem, the owner needs to wave it in the name of Hashem, who then gives it to the Kohen; whereas it refers to the Shok as 'Shok ha'Terumah' since they are now separating it from their own portion to give to the Kohen.
See Ba'al ha'Turim on Pasuk 30 and refer also to Sh'mos 29:24:2:1* & 29:24:3:1.
Why does the Torah use a Lashon Matanah ("Va'etein osam") in connection with the Chazeh ve'Shok?
Yerushalmi Yevamos, 8:1: To teach us that, like a Matanah, the Chazeh ve'Shok will never be annulled. 1
The question arises as to why the Mitzvah of Chazeh ve'Shok could become Bateil more than any other MItzvah. See also Torah Temimah, note 139, who raises a number of other problems with this D'rashah,.
What is the word "va'Etein Osam" coming to preclude?
