Комментарий к Вайикра 20:22

ושמרתם את כל חקותי, "And you shall observe all My statutes, etc. The reason the Torah had to repeat this verse although we have read it already in 18,26 is to urge us to ensure that the statutes do not become abolished in practice through failure of either oneself or others to observe them. Observance of the statutes insures that the land will not spew you out. If the community one lives in fails to protest non-observance of these חוקים by others one will still be subject to the land spewing out its inhabitants even if personally one had been meticulous in one's observance of Torah law.

You shall keep all of My statutes. We have explained that keeping the statues and the laws, which are the Talmudic questions and answers, protects a person that he will not come to the point of illicit relations. Here, Scripture adds that even if, Heaven forbid, the generation is lax about illicit relations, and this is a cause for exile from the Land of Israel, nevertheless, if they are diligent in Torah study then the merit of the Torah will assist that the Land of Israel will not vomit them out. Rather, they will be punished at that time in the Land of Israel. This is stated in Nedarim (81a) in reference to the verse (Yirmiyahu 9:11), “Why is the Land of Israel ruined? …” — this matter was asked to the wise men and to the prophets, and the response came in the words of Hashem (ibid. 12), “Because they have forsaken My Torah.” Although it is known that during the Destruction of the First Temple there was idolatry, illicit relations, and bloodshed, in any case, if it were not for forsaking the Torah the Land of Israel would not have been completely destroyed.

ושמרתם את כל חקתי, “and you are to observe all My statutes.” You must not violate any of the commandments involving sexual restrictions and incest. (bn Ezra)

ואת כל משפטי, “and all My instructions concerning penalties for transgressing these laws,” by your judges seeing to this.

ושמרתם את כל חקתי, “the reason why the Torah has repeated this phrase once again, is to remind the people that G-d’s statutes apply in the Diaspora as well as in he Holy Land. In this verse only the statutes applicable in the Holy Land are meant.
