Why does the Pasuk say "Ki Ani Hashem Elokeichem" before commanding Yisrael to be holy?
Hadar Zakeinim (24): "Ki Kadosh Ani" - if one is holy, it is proper that His servants be holy. Da'as Zekenim (45) - this is like the Piyut says, 'Na'eh li'Kadosh Pe'er mi'Kedoshim.'
Why does the Torah repeat "Vi'heyisem Kedoshim"?
Rashi: The Pasuk is saying that if you comply and live with Kedushah, then Hashem will sanctify you in Heaven and in the World to Come. 1
Moshav Zekenim #1: Angels are called "Kadishim"; they have no Yetzer ha'Ra. People have a Yetzer ha'Ra, so Hashem added a second Kedushah for them.
Moshav Zekenim #2: A parable for this is a king whose nation made three crowns for him. He put one on his head, and put two on his sons' heads. The angels crown Hashem with three Kedushos, and He put one on His head, and two on the heads of Yisrael.
Yuma 39a: If one is Mekadesh himself a little, [Shamayim] is Mekadesh him a lot. If he is Mekadesh himself below, they are Mekadesh him above, If he is Mekadesh himself in this world, they are Mekadesh him in the world to come. Lev Eliyahu (Shemos p.64) - one who fulfills the Torah amidst poverty (of understanding, yet he fulfills properly), in the end he will fulfill amidst wealth (Avos 4:9). I.e. Hashem will give to him great understanding.
Why, in the current Pesukim, does the Torah issue a number of La'avin with regard to eating Sheratzim?
