Leviticus 26:15

Apostasy. So these are 7 sins, the first leads to the next and so on till the 7th. They are as follows; not to study, not to perform, abhorring others who do the commandments, despising the scholars, preventing others from their performance, denying the commandments, and apostasy

and if you despise My statutes, and hate in your soul the orders of My judgments, to do not all My precepts, but your purpose be to abolish My covenant;

nullifying This is an irregular word. Verbal nouns often deviate from the normal construction.

AND IF YE SHALL REJECT MY STATUTES. Because “statutes” are commandments the reasons for which have not been revealed to the majority of the people, therefore fools reject them, saying: “Why does G-d desire that I should not wear this garment which is woven with threads of linen and of blue wool? And how do we benefit by burning the [Red] Heifer, and sprinkling upon us the ashes thereof?” The “ordinances,” however, everyone desires and everyone needs, for there can be no civilized life for any people or country without ordinances. No one will reject the ordinances of: he that smiteth a man so that he dieth; and if men strive together;, Verse 22. and the laws of the ox and the pit, Verses 28-37. and the [four] guardians,, 22:6-14. and so on. However, the judgment that we execute upon those who transgress the commandments, such as one who has forbidden sexual intercourse, or profanes the Sabbath, or does [the sorcery of] the ov or yid’oni they will despise, because of [the necessity of keeping these] commandments, which constitute a heavy yoke upon the wicked. Therefore He said, and if your soul abhor Mine ordinances so that ye will not do all My commandments, for their abhorrence of the “ordinances” is in order that they should not keep the commandments.

THAT YE MAKE VOID MY COVENANT. [This means that they desire] that the covenant be completely voided so that they will thus be without Torah, in order to permit themselves openly forbidden sexual intercourse, and every desire which is sweet to their soul. By way of the Truth, [the mystic teachings of the Cabala], the verse means that this covenant will be made void and annulled, [this being] the opposite of [the Divine assurance], and I will give peace in the Land. It is with reference to this that He said, forasmuch as they voided My covenant, although I ruled over them, [meaning that] “because they annulled My covenant of peace, I Myself ruled over them.”

ואם בחקותי תמאסו, that you do not only ignore them but actively despise them;

ואם את משפטי תגעל נפשכם, if you treat them as a person who deliberately spits something out because he detests it. You would not have any objective reason to do this as you are familiar with the purpose of such commandments, knowing them to be fair and just.

לבלתי עשות את כל מצותי, your supposed detestation of My commandments was not an objective evaluation of them, but a signal that you wanted to throw off the yoke of Divine legislation, a deliberate act of disobedience. Our sages have often stated that the Israelites who worshipped idols were perfectly aware that these idols were totally helpless, could not help themselves, much less those who professed to worship them. If they worshipped them in spite of knowing that they were all nothing but sham, it was only in order to anger G’d. They did so in order to be free to practice incest in public. (Sanhedrin 63) The Prophet Hoseah 5,4 states explicitly when he writes: “their habits do not let them return to their G’d because of their lecherous impulse within them. They pay no heed to the Lord.”

להפרכם את בריתי, in order not to be different from the other nations surrounding them, neither of whom have been burdened with ethical/moral legislation and rituals such as demanded of the Jewish people by the Torah. The prophet Ezekiel, in Ezekiel 20,32 already challenges the people who would use the fact that they were now in exile, apparently abandoned by their G’d, as an excuse do divest themselves of the claims the Torah makes on them. He accuses them as making all this an excuse to serve deities made of wood and stone.
