ומל ה' אלוקיך את לבבך, “the Lord your G’d will circumcise your heart, etc.” Nachmanides writes on this verse: “this means that the Lord will remove the ‘foreskin’ covering the people’s heart”, a simile for desires of sexual and other varieties which are described as ערלת הלב. We know that someone who is captive to such desires is known as ערל, from Jeremiah 9,25 where the prophet describes the Jewish people as being of uncircumcised heart [although they do not have a foreskin on their sexual organ. Ed.] Just as the removal of the foreskin of that organ helps to restrain excessive sexual urges, so the removal of its equivalent covering of the heart will control the cravings responsible for committing other sins. G’d assures the people in that verse in Jeremiah that a time will come when such obstacles to obedience to G’d’s laws will be removed. [Although what the author wrote here is the gist of what Nachmanides writes, it does not represent an accurate translation of his words. Ed.]

והקמתי את בריתי אתכם AND I WILL ESTABLISH MY COVENANT WITH YOU — a new covenant; not like that covenant which you broke by worshipping the golden calf), as it said, (Jeremiah 31:31-32): “[Behold, the days come, saith the Lord that] I will make a new covenant with the house of Israel, and with the house of Judah. Not according to the covenant [that I made with their fathers,… which My covenant they broke, but… I will put My law in their inward parts, and write it in their hearts]” (Sifra, Bechukotai, Chapter 2 5).
